This is a turn-based strategy/RPG game set in the stars. In the early stages, you will recruit a team of experts on Earth for exploring a distant alien homeworld, choosing between scientists, mutants, and soldiers. Scour the planet for lost alien technology and uncover the secrets to Earth’s doom.
Dark, Story-driven
It is 1979 and aliens are invading a Cold War Earth. You run the whole defence: interceptors scramble against UFOs, scientists pull apart captured tech, and small squads of expendable soldiers fight tense turn-based battles on fully destructible battlefields. No scripted missions, so every war plays out differently. Brutal, absorbing, and hard to put down.
Tense
You run X-COM, the world's answer to an alien invasion: shoot down UFOs, lead soldiers through their wreckage, and turn captured tech against the invaders while governments threaten to pull funding. A tense, punishing 1994 strategy classic where every decision, and every loss, sticks with you.
Dark, Tense
