Alien Artifacts (Long War)

This page may be outdated. It is up-to-date for version b15e. The latest version is 1.0.

Some Artifacts that previously had no value are now used by the game as prerequisites for research projects or Foundry projects, particularly Alien Stasis Tanks and Alien Surgeries. Within the Gray Market listings, the green text "This item has no research benefit, and can be sold freely" is still correct in that these items will never be a part of any research project, Foundry project, or as a prerequisite for manufacturing any items. However, you may still get pending resource requests for some of these items from XCOM countries. As an example, Alien Entertainment can be requested by a country in exchange for panic reduction.

Beyond that, the changes are mostly to the Gray Market values for these resources. Acquisitions from Alien Base assaults and the EXALT HQ are much more valuable, encouraging XCOM to liberate withdrawn nations when possible and forcing the player to consider the benefits of selling these resources for quick cash versus possibly fulfilling later country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.

Another notable difference is that alien weapons obtained through stunning enemies with the Arc Thrower cannot be used directly, but are consumed to manufacture XCOM plasma weapons, including interceptor, SHIV, and MEC plasma weapons. 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. 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.

• 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 requires a Plasma Dragon, which needs an Alien Heavy Weapon to make.

Alien materials

These materials are required in large numbers for almost all production that is based on alien technology.

Alien weapons

These weapons and grenades can be studied, so that XCOM can craft their own plasma weapons, which require additional captured weapons as crafting materials.

Captives

From time to time, you will receive a council request for a captive alien. 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 when you tear down the Alien Containment facility, all Alien captives are killed.
