{{Toc_(LW2)}}Research in LW2 proceeds much the same way as in vanilla XCOM 2, but is expanded.
{{Toc_(LW2)}}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.

Revision as of 20:25, 10 September 2020

Long War 2 Main Page

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.

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, counts 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.

Xenology

These projects study the aliens' capabilities in a way that doesn't fit in other categories.
