XCOM 2 Facility Powercore.png

The Power Core of the Avenger doubles as its main Research laboratory, headed by Dr. Tygan. Research in Long War 2 has been expanded with two more weapon tier techs, one more autopsy, and more Proving Grounds projects unlocked by autopsies.

  • Unlocked items in bold don't need any other project, while items in italics need another research or Proving Grounds project to be fully available.
  • Projects with a yellow background form part of the Golden Path: the elements that progress the storyline.

Research Time

The time to research a project is based on a points system: each project has a required amount of points to complete, and each hour a number of points is added depending on the number of scientists in the Avenger and how they're staffed.

At the start of the game, the only contribution to research comes from Tygan, counting as a scientist contributing 10 science points per hour, but he cannot be assigned to any scientist staff slots. Each additional scientist contributes another 5 points per hour, increasing to 10 if they're working in a laboratory, but if they're staffed in any other facility, they won't be able to contribute to research.

The "Basic Research" project will increase the base points per hour by 5, and it is infinitely repeatable, but each completion increases the cost of the next one by 2800 points.

Basic Projects

These projects increase XCOM's efficiency at research and engineering, reducing staff requirements and increasing speed. They can be repeated indefinitely, but each time they are completed the time for the next repeat increases.

Alien Autopsies

Once Alien Biotech has been researched, corpses recovered from some missions can be autopsied. If enough corpses are available, the autopsy will take no time to complete, but only one corpse will be consumed.

ADVENT Autopsies

Once Alien Biotech has been researched, corpses recovered from some missions can be autopsied. If enough corpses are available, the autopsy will take no time to complete, but only one corpse will be consumed. These also include mechanized units, which can be broken down after their robotics have been investigated (which doubles as drone breakdown).

Shadow Chamber Projects

These projects form a major part of the storyline, beginning when either the Blacksite mission is completed or when a Codex Brain is recovered from Skulljacking an ADVENT Officer. The first of these unlocks the Shadow Chamber, a facility needed for every project afterwards. These projects cost Intel, and they all belong to the Golden Path: they will unlock further storyline missions, including the final ones.
