Finish X-COM: UFO Defense

The underwater sequel, harder than the original in every way.

One city, two alien factions and a real-time mode; the last X-COM the original team made.

Firaxis reboots X-COM with 95% shots that miss; the turn-based tactics revival.

Earth lost; run a resistance from a flying base with timed missions.

Three named alien hunters who remember your fights, plus three resistance factions to answer them.

From a settler to Alpha Centauri, one more turn at a time; Sid Meier's masterpiece of 1996.

Tesla coils, Tanya and full-motion video generals; Westwood's alternate Cold War.

A physicist teleported to an alien planet; Eric Chahi's wordless cinematic game.
