Firaxis have announced that they will be partnering with the newly formed Long War Studios. Comprised of a small team that developed the Long War mod for XCOM: Enemy Unknown, the group is already developing multiple mods to be ready (hopefully) by the time XCOM 2 launches on February 5.
Further details of the partnership are vague, however, more information is promised “soon”. At the very least, we are sure to gain further insight on January 30 when Firaxis hold their panel at PAX South. Gameplay and information regarding XCOM 2’s modding tools are set to be shown at this event.
Long War Studios are also developing their own projects. Their first, titled Terra Invicta is a “grand strategy game in which the player leads the defense of Earth during an alien invasion.” that is currently in pre-Kickstarter development. More information on Long War Studios and their projects can be found on their website.
