X3: Terran Conflict
Trade, fight and manage your way from one small ship to a sprawling space economy in an open galaxy.
Loved how retro and tense X-COM: Interceptor can get? These games line up well for what comes next.
Command Earth's last defense against a global alien invasion. Build out your underground base, research alien tech, and lead a hand-picked squad in tense turn-based firefights where one bad move can cost a veteran soldier for good. Losing hurts, which is why winning feels so good.
Tense
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.
Retro, Tense
The year is 2938 and Earth has finally met the X Universe, with trade flourishing and tensions rising. Start with one small ship and a handful of credits, then trade, fight, board and build your way to an empire in a living galaxy where every haul, factory and fleet is yours to command.
A space sim with a story about Julian Gardna, but the real game is the universe itself: over 130 sectors to explore, 60 ships to fly, asteroids to mine and factories to build. Start with one small ship and a thin wallet, end up running a trading empire, or hunting the Khaak. It takes patience to learn, and it pays you back for years.
