Long War 2 Beginner Tips: Read before starting your first X-COM 2 LW2 Campaign! (Havens, Resistance, Supplies, Intel, Liberation Missions and more)

Long War 2 Beginner Need to Know Info Before Starting a Campaign

Beginner strategy for Long War 2! This free mod for XCOM 2 increases the time, complexity, and difficulty of the XCOM 2 campaign. While it is an amazing mod, one of its downsides is that the new geoscape and other mechanics are not explained well enough. This article will be a quick primer of the information that every player should know before starting a Long War 2 campaign.

Before Starting Long War 2: Setup, Installation, Mods, Workshop

This article does assume that you have played the original X-COM 2 campaign and are fairly familiar with how X-COM 2 works in general. If you haven’t I would recommend playing through the original vanilla XCOM 2 campaign first.

Installing Long War 2 is thankfully much easier than the original Long War was. Simply go to the Steam Workshop, find the XCOM 2 section, then find the Long War 2 mod. Note that you do NOT want to download the mod pieces like the Long War 2 Alien Pack etc. Just click subscribe on the Long War 2 mod and then check your downloads tab to ensure it is also downloaded.

At this time you may also want to install some other mods that are compatible with Long War 2. I have written a separate article that sums up what mods you should really use and I have fully tested them with Long War 2 over dozens of hours.

Gathering Supplies at Resistance Havens

In Long War 2 you now gather supplies by recruiting members at resistance havens, then setting them to the “supply” task. Each day, the supplies gathered are added to your supply drop which occurs every 20 days.

When you look at a Haven in the world map you will see $X ($Y) next to the haven name.  The first number ($X) is the amount of supplies you have banked so far in this supply drop period. The second number ($Y) is how much you should generate in that region by the end of this supply drop period.

You can also get a small and unreliable amount of supplies from mission rewards or by selling corpses and loot in the Black Market like in the original vanilla game. Remember that corpses and loot drops are needed for some research and engineering projects though so don’t sell them all.

“Unknown Source” Stealing Supplies – Spies, Infiltrators

This is probably the most confusing aspect of the game, but is pretty important to understand. Some people consider revealing information about this to be a spoiler to the game, but in my opinion it is so vital to your campaign’s success that you should know about it before starting. At random when you recruit a new member at any Haven, it may be an infiltrator. Each day when your supplies are calculated, the game looks to see if you have any hidden infiltrators present. If so, a percentage of the supplies you earned will be siphoned away. You won’t know how many supplies you’ve lost to this mechanic until the Supply Drop happens and there’s no way to know which members are infiltrators on the Geoscape world map.

How to Stop Losing Supplies and How to Reveal Faceless Infiltrators in Long War 2 (Resistance Spies)

Once you see that you’ve lost supplies to an “Unknown Source” in the supply drop, you know you have a Faceless Infiltrator in one or more of your havens. Unfortunately there is no real way to know which haven(s) this is happening in. In order to reveal and eliminate this infiltrator you have to station a soldier as an Advisor in your haven(s). Generally you will want a soldier advisor there most of the time in the early game anyway, since they also speed up the “Recruit” task and help fight on certain missions. Higher ranking soldiers are better at revealing infiltrators. Higher ranking Officers are even better, and Psionic soldiers are the best at revealing infiltrators.

When a soldier advisor is stationed, there is a small chance they will generate a mission over time where you interrupt a spy rendevous with the Advent. It may take 1 week or 2 months etc. depending on random chance and the soldier rank. The popup will be red and the description will clearly state that you are interrupting a spy meeting. If you accept that mission, you go in with your Soldier Advisor and a few of the resistance members. Note you don’t get to change loadouts before launching the mission. The enemies in this mission usually consist of 2 groups of enemies. Each “pod” will have 3-4 advent troopers, officers, or faceless, plus there will be 1-2 enemies that turn from civilians into faceless. Those are the infiltrators that you are there to kill.

During the Early Game You NEED to Focus on Liberating a Region!

After two long Long War 2 ironman campaigns, the one biggest thing I can recommend is that you focus immediately on Liberating a region. Not only does this advance the story and reveal the end-of-game timer, but more importantly you really need that reliable source of supplies. The Advent Strength slowly increases as the game time progresses which will make it harder and harder to liberate regions.

Ideally you want to be well on your way, possibly done liberating a region in May or June according to the in-game calendar. If you get to September or October without liberating a region it might just be too late!


Assign Resistance Members to Intel and Recruit in the Early game, NOT Supply!

This is kind of a trap. Early in the game you think that you need supply to recruit soldiers and start upgrades and facility construction. However what you really want to do is focus on intel gathering until you liberate a region. Recruiting will help you recruit some additional resistance members so that they can also be assigned to intel. You will still be generating some supplies by selling corpses and other loot. Also until you get higher ranked soldiers, you will be unlikely to be able to reveal faceless infiltrators so your resistance members on supply will be generating less anyway.

How to Liberate a Region in Long War 2

This is another problem with the current state of Long War 2. The process to liberate a region is super unclear, but is vital to a successful campaign. Not only that, but you need to do it early on, but might not even know that you should be prioritizing it or even that its a possibility.

In order to liberate a region (for example South Africa or East Asia) you need to first set resistance members to the “intel” task. Flying the Avenger to the region then scanning adds extra intel gathering and assigning a scientist as the Haven Advisor also increases the effectiveness of resistance members on the intel task. With more intel gathering you will see increased amounts of available missions popping up in that region and the mission expiration timers will often be longer. The result from changes in intel assignments seems to generally be delayed by a couple of days. Once your first haven has about 6 or 7 members I would set them all to intel, set a Scientist advisor, and scan with the Avenger at that location until you start the liberation mission chain.

On the Geoscape / world map, at the start of the game, you will probably see “Find a Lead” as your objective listed in the upper left. This isn’t really explained and is really pretty confusing–I really think they should add some explanation somewhere to clarify how this works to new players. Regardless, when you have your resistance members searching for intel, eventually you will see a mission pop up with only Intel (not an intel package) listed as the reward and in the description of the mission it will mention a lead. If you complete the objective of that mission successfully, you should be able to start the Liberation mission chain. Again this is not clear and is not explained in game much, but that’s what this article is for! Finding and completing this mission should be your number one priority in any new Long War 2 campaign!

The Liberation Mission Chain – How to Recognize each Mission

Update: I’ve written a separate, full article specifically focused on revealing, recognizing, and completing liberation missions: How to Identify Liberation Missions in Long War 2 XCOM 2

  1. Liberation mission 1: Hack an Objective (workstation etc) recover data cache etc (the reward will be ONLY Intel, not an intel package and no other reward and will mention a “lead” in the description – that is how you can identify a mission popup as the first liberation mission.) See the image below for an example of what to look for. Your squad starts this mission in concealment.

  2. Liberation Mission 2: Rescue a friendly VIP from a vehicle or jail – advent strength increased by +3 from baseline. No concealment on this mission.
  3. Liberation Mission 3: Destroy Relay or Kill/Capture enemy VIP  advent strength increased by +3 from baseline. Note on the capture enemy VIP mission type there is a higher chance than usual that civilians will turn into Faceless enemies. REWARD: Intel and immediately after completing the mission it will reveal mission #4.

  4. Liberation Mission 4: Secure Network Tower – destroy network tower. Reinforcements will be called in during this mission so be ready. Tough mission. When I did this it was impossible to sneak past any enemies due to the patrol pattern and map layout. Reinforcements start coming in shortly after you are revealed as well. This mission allowed me to bring in a maximum of 5 soldiers and had no expiration (so you could infiltrate to 200%) REWARD: Location of Advent Regional HQ (reveals mission #5 immediately after completing this mission) and some Intel. Squad starts concealed.

  5. Liberation Mission 5: Final Mission: Assault Regional HQ – this will be a mission with many enemies and will be usually be very tough. Luckily you can take in a full squad of 8-10 soldiers if you want, and there is no expiration so you can infiltrate to 200%. Unfortunately enemy activity will likely be very high, possibly “Swarming.” There will also probably be a General (very strong officer/captain) defending a building at the far end of the map. Once you complete this, the region will be liberated permanently. Advent will no longer attack the haven there and you can safely recruit up to 13 members then set them all to supply for maximum supply generating. If you don’t liberate the region and try to generate a lot of supplies from it, eventually the aliens will attack it and there is almost no way to prevent them from killing at least 4-6 (or more) members each time that happens. Squad starts concealed on this mission.

How to Recruit New Resistance Members at Havens in Long War 2

To recruit new members, set one or more members at the haven to the “recruit” task. Assigning a soldier as an advisor increases the speed or chance that you will recruit new members. Doing this also gives you a small chance to have a new soldier available for recruit in the Armory. Higher ranking soldiers recruit new members faster.

If you happen to be unlucky and all of the resistance at a haven are wiped out during a mission, you can still recruit new members by stationing a soldier as an advisor. However this will probably take a while to get your first new resistance member, like 2-4 weeks.

How Infiltrating and Intel Gathering Works In Long War 2

When you set resistance members to gather intel, they contribute to finding missions, and finding them with more time left on the mission expiration timer. Generally you will only want to accept missions that you can reach at least 100% infiltration on with 4-6 soldiers. This means the mission timer needs to be about 5-6 days at least. The more intel gathering you are doing, the more likely it is you will reveal a mission when it still has a high timer.

Baseline enemy activity tells you how many enemies you will encounter if you infiltrate to 100% (your infiltration time must be lower than the mission expiration timer). You can always boost infiltration by 75% whenever you want at the cost of 25 intel. This can let you do vital missions that otherwise would be extremely risky or impossible.

  • 6-9 enemies: Extremely Light
  • 10-12 enemies: Very Light
  • 13-15 enemies: Light
  • 16-18 enemies:  Light-Moderate
  • 19-21 enemies: Moderate
  • 22-24 enemies: Moderate-Heavy
  • 25-27 enemies: Heavy
  • 28-30 enemies: Very Heavy
  • 30-32 enemies: Extremely Heavy
  • 33+ enemies: Swarming

Only accept missions with Baseline Enemy Activity of Extremely Light or Very Light (In General)

This is a general concept, but generally only accept missions that you can infiltrate with 5-6 soldiers, reach 100% infiltration, and have a baseline enemy activity of Extremely Light or Very Light. To reach 100% infiltration with a decent squad, the mission will need to have around 6 days or more left on its expiration timer. However there will occasionally will be times where you break this rule.

If you are able to reach 125% infiltration, enemy activity will decrease by one level from the list above (e.g. “Light” to “Very Light.”) At 150% infiltration, it decreases by two levels, and at 200% it maxes out at 3 levels decreased. In actual practice it was generally good if I could reach 100 or 125% infiltration, with Extremely Light or Very Light enemy activity, and 5 or 6 fully equipped soldiers. If it met those criteria I would consider doing the mission if the rewards were good.

Bookmark and Get Familiar with the Infiltration Calculator

This is another big issue I have with Long War 2. There’s no reason that it should be necessary to use a separate calculator in order to properly play and use strategy in the game, but as of right now this tool is vital. The infiltration calculator, made by xwynns allows you to plan during squad select so that you can hit the desired infiltration percentage. Without this there is no real way to plan what soldiers and equipment to bring if you plan to use intel to boost infiltration speed. Hopefully the LW2 devs will update the mod so this is not necessary.

Here’s the link to the Google Doc version of the infiltration calculator. As mentioned there, once loaded, you need to go to File > Make a copy then save it to your account so that you can edit it.

Covert Missions – Avoiding Combat Altogether

Update: Long War 2 was updated to now have more numerous, but smaller patrols. Previous versions often had 4-5 enemies per “pod” but now you will more often see 2-3 enemies per pod. Full-stealth missions are now harder to pull off because there are more pods on (mostly) random patrol.

It is possible to stealth through some missions by remaining concealed until you reach your objective. Then, complete the objective (for example hack a workstation) and call the skyranger on the same turn. Play defensively using hunker down, smoke grenades, etc, until you can evac.

Depending on the timer and enemy activity, you may only realistically be able to infiltrate with 2-3 squad members in the time allowed before a mission expires. Normally would simply ignore those missions, but it is an option to try completing it with stealth. One strategy is to use your new squaddies for these high risk missions and bring mostly to Shinobi and Specialist classes.

Covert / Stealth Mission Tips in Long War 2

You can equip soldiers with SMGs so they can move farther. Bring a specialist so you can remotely hack or access the objective and be careful and avoid patrols.

Using this strategy its possible to successfully complete way more missions than you otherwise would be able to. Normally you have to commit a full squad of 5-8 soldiers for about one week in order to do a single mission. If you’re able to scrape through a mission with stealth you can complete a mission with only 3-4 members within 2-4 days.

Also important to know: in Long War 2, soldiers gain experience mostly by completing missions, NOT by getting kills. Kills do still grant some experience, but its much less than in the vanilla game. You also get an experience boost if you complete all objectives without any wounded soldiers. This allows you to get a huge experience boost in stealth missions without needing to kill any enemies.

You need to skip some (many) missions (often)!

Again this is not really explained in game. In previous XCOM games you generally took every mission that popped up unless things were going very badly for you. In Long War 2, you need to carefully consider if doing a mission is worth it to you.

In the early game your number one priority needs to be finding and completing the liberation missions for at least one region. You should be able to safely de-prioritize and avoid missions with only soldier recruits as a reward. During the early game they will be low level recruits and you should be able to just recruit enough new soldiers from the Armory.

Take only the highest priority missions with the best rewards. Early on you may really need an Engineer, Scientist, or Enemy Materiel (supplies, alloys etc). Around the middle of the campaign, intel as a reward becomes very important. Generally I find Soldier and Resistance Personnel rewards to be the least important and usually don’t take those missions.

Rethink Playing on Ironman for your First LW2 Campaign

I love Ironman in the XCOM games. I played both of my main Long War 2 campaigns in Ironman on Veteran difficulty (no reloading and the game saves automatically). I definitely feel like in XCOM 2 Ironman mode helps you get really attached to your soldiers and makes missions very tense.

However Long War 2 is very long. Too long to waste time on a doomed campaign, and the way the game works you may not know you are in a doomed campaign until 50+ hours in.

As a sidenote, most people will probably end up restarting LW2 at least once before completing a campaign. It just takes a few months of in game time to really understand the mechanics.

How Long Does a Long War 2 Campaign Last?

A full LW2 campaign will take about 100 hours to complete.

Based on my experience I would say you have until about late October or November in game before the game ends unless you complete some story objectives, raid facilities, or counter Dark Events that set back the Avatar project timer.


Any corrections or comments are very welcome! I’ve spent a lot of time with X-COM 2, Long War 2, and the other X-COM games and I’ve also done a lot of research. However I’m sure I have more to learn and there are other players out there with differing or better strategies so I’d love to hear them! Post in the comments below and I’ll answer any questions you might have.

    Thanks! Glad you got some use out of it. I’m excited to see they continue to release updates for Long War 2 with balance fixes and more features.

  3. Jet Sunstrider says:

    Oh my gosh… this truly helped me out, big time. I remember on my first try of LW2, I was so confused on how everything worked my first campaign became doomed before my first retaliation strike mission. I had no idea what the “find a lead” thing was all about. Thanks for this, I’m defiantly sharing this on Twitter.

  4. Chris says:

    For the life of me, I cannot figure out how to place an advisor in a Haven. This is my first play through of LW2, and I didn’t even know what was going on. But every time I try to place or move an advisor, it tells me I can’t because there are active missions in the region.

    I am completely stumped.

  5. daydull says:

    Make sure the soldier is not assigned to a squad (if so remove them from the squad.) Also make sure the soldier is not infiltrating or on a mission or otherwise busy with training etc. Their status should be “available” and they shouldn’t be in a squad before you try to select them for the advisor spot.

    Hope this helps!

  6. Chris says:

    I figured it out. Apparently I somehow started a new game in vanilla. I didn’t realize it had to say LW2. So when I logged out and then started it up last night, it said LW2, and caused all sorts of problems. So I just gave up and started over, and everything is copascetic now.

    Thanks though.

  7. Raz says:

    This guide has been amazing. The only problem (and great frustration) that i encountered is that I did not expect 25 enemies in a single mission, with me having rookies, at the literal start of the campaign. I only stumbled across Long War because I was looking for a marathon mod for XCOM 2. It had long in the name and I was excited. But I didnt expect this. Really enjoyable mod, but a bit too unforgiving for new players, mostly because of lack of clarity on what the effing heck you need to be doing. And that’s where you came in. Thank you for all the tips and clarifications. Amazing article, and will show it to everyone I know that plays Xcom.
    Amazing job!

  8. daydull says:

    Thanks! I completely agree, the mod could definitely use some work on making the changes more apparent and understandable. I think everyone has a similar horrible experience the first time they play Long War 2.

  9. Charalampos Koundourakis says:

    Excellent article!

  10. ltwinter says:

    excellent article, i am experienced in Xcom and love the game, and never usually save. LW has been super frustrating, and despie reloads it is almost impossible to cpmplete with early squads as I didnt know what infiltration meant and ignored it – going in to heavy enemy resistance is an exercise in futility with Rookies !

    thanks – its clear and helpful !!

  11. Vince DeRo says:

    Thank you this helped a lot.

  12. Smolders says:

    Wish that I had seen this guide before spending dozens of hours trying to figure it out on my own. The liberation thing is not intuitive and the mod does jack all nothing to explain or stress its importance. Thanks for the guide!

  13. Greg says:

    I got the secure Network Tower mission, infiltrated to 200%, but then the mission WON’T LAUNCH!! I might have missed the Find a Lead mission (if that’s possible), but still.
