Alien Artifacts (Long War)

Alien Artifact is everything that your soldiers return to the base from tactical missions.

Gray Market values for the artifacts are changed from vanilla. Acquisitions from Alien base assaults and the EXALT HQ are much more valuable, encouraging XCOM to liberate withdrawn nations when possible and forcing the player to consider the benefits of selling these resources for quick cash versus possibly fulfilling later country resource requests.

• Note that the Fusion Core and Outsider Shard are only needed to unlock their associated research - the unlocked research does not use up one of these artifacts.
• Enhanced Plasma Foundry project requires a Plasma Dragon, which needs an Alien Heavy Weapon to make.

Alien materials

These materials are required in large numbers for almost all research into, or production of, alien technology.

Alien weapons

Unlike vanilla, alien weapons obtained through stunning enemies with the Arc Thrower cannot be used directly; instead these weapons and grenades can be studied, so that XCOM can craft their own plasma weapons, which require additional captured weapons as crafting materials. Alien Rifles (from captured Mutons and Heavy Floaters) are used in the production of most plasma weapons (including the Plasma Rifle, Plasma Novagun, and interceptor Plasma Cannon). Alien Carbines (from Floaters, Outsiders, and Thin Men) are used in the production of the lighter XCOM soldier weapons such as the Plasma Carbine and Plasma SMG. Alien Heavy Weapons (from Muton Elites) are used in the production of the MEC and SHIV plasma weapons. Additionally, some of these alien weapons may be required in order to perform the associated plasma research in the first place.

Alien devices

These devices are gained when successfully completing a crashed UFO, landed UFO or Alien base assault mission. They are used in a variety of research and production projects (e.g. Firestorms), and XCOM nations may start requesting these devices once certain preliminary research is performed. Two devices that previously had no value are now used by the game as prerequisites for a Foundry project, particularly Alien Stasis Tanks and Alien Surgeries. Alien Food still has no use, while Alien Entertainment can be requested by a country in exchange for panic reduction. Alien Stasis Tanks and Alien Surgeries can be requested in exchange for scientists. The damaged versions of items (as well as Alien Food) can be sold freely; XCOM nations will never request them.

Aliens

In Long War, you need more than a single corpse or wreck to perform an autopsy. Many corpses and wrecks are also required for additional research and production. With China's Xenological Remedies starting bonus, the sell values of corpses and wrecks are doubled.

You only ever need a single captive to perform an interrogation though. From time to time, you will receive a Council request for a captive alien you have already interrogated. These are almost always great deals, and since you don't need the captives after the initial interrogation, it is recommended to accept these deals at all times. Note that if you tear down the Alien Containment facility, all alien captives are killed.
