Twenty years ago, the aliens arrived. XCOM — humanity's last defence — was defeated. The aliens now rule Earth, with human collaborators managing an alien-designed utopia that masks something far darker beneath its surface. XCOM still exists, scattered and hunted, operating from a stolen alien ship called the Avenger. Your mission is to rebuild the resistance, contact underground cells across the globe, and uncover the truth behind what the aliens are really planning before it is too late.

XCOM 2 is a turn-based tactical strategy game played across two layers — the strategic layer and the tactical layer. On the Avenger, you manage resources, research alien technology, recruit soldiers, contact resistance cells and race against a global doom clock called the Avatar Project. On the ground, you command squads of four to six soldiers through procedurally generated maps, using cover, flanking, concealment and a deep class system to eliminate alien threats. Death is permanent — a soldier lost on a mission is gone forever, adding genuine weight to every decision. The War of the Chosen expansion adds three powerful enemy champions, new resistance factions, exhaustion mechanics and a hugely expanded mid-game. Steam Workshop hosts thousands of mods, from cosmetic soldier customisation to total overhaul campaigns. One of the most moddable tactical games ever made.
