(The Allies Unknown mod tanks LW2 and LWOTC hard, and so I have balanced this mod with the assumption that it won't be used.)

- Aliens can be acquired through Covert Actions. You won't typically get one right away but they show up quickly enough. Once you start seeing them, you should get at least one per month from one of your factions. The Covert Actions cannot fail and don't require soldiers of a particular rank, but they can still get injured. Also, you don't just GET the alien like you would an Engineer or Scientist; you have to do a mission that the Covert Action unlocks.

- As of the March 3rd 2021 update, the mission has been overhauled once again. It now uses the base game WOTC mission GatherSurvivors (a Resistance Ops mission). This is a proper Quick Response mission, which now uses a custom encounter list and lets you send up to 8 soldiers. XCOM starts the mission revealed. The Lost will also appear if you're at a high enough Force Level to encounter them. The alien is the primary VIP you need to rescue to succeed in the mission (be careful with them, they don't spawn with any plating, although they CAN help fight). There are also a couple of resistance operatives you can find in the mission who you can give orders to, but they do not join your crew as Rebels or Rookies even if you extract them. They have a standard Rookie loadout of Assault Rifle, Ceramic Plating, Frag Grenade and Flashbang. Once you make contact with the VIP, a fixed evac will appear on the map for your squad and rescuee(s) to extract. When the mission spawns, you have 4-5 days to address it or it will disappear. As long as you have the required [WOTC] Sensible Mission Penalties mod, you won't lose region contact if that happens.

- As of April 16th, 2021, in addition to the above mission, you can also get the WOTC versions of Rescue or Extract. These do not have custom spawn schedules at all.

- If you either can't do the Covert Op due to bugs, or otherwise just don't want to do it but still want to play with aliens, you can use console commands to spawn them into your barracks. Note that doing so will not allow them to get NCE rolls. (I don't actually know at this point.) They spawn at Squaddie rank. The commands are as follows:

• AddAlienRecruit PA_Archon
  
• AddAlienRecruit PA_Andromedon
  
• AddAlienRecruit PA_Berserker
  
• AddAlienRecruit PA_Muton
  
• AddAlienRecruit PA_MutonHunter
  
• AddAlienRecruit PA_MutonProwler
  
• AddAlienRecruit PA_MutonHarrier
  
• AddAlienRecruit PA_MutonBeleaguer
  
• AddAlienRecruit PA_Naja
  
• AddAlienRecruit PA_Sectoid
  
• AddAlienRecruit PA_Sidewinder
  
• AddAlienRecruit PA_Viper2 (this is not a typo, it needed to be done to ensure Viper Class Overhaul didn't do any hardcoded changes to this mod's Viper)
  
• AddAlienRecruit PA_Faceless
  
• AddAlienRecruit PA_FrostAdder
  
• AddAlienRecruit PA_FrostBomber
  
• AddAlienRecruit PA_FrostNecromancer
  
• AddAlienRecruit PA_SectoidAbjurer
