Space Impossible delivers a rich, procedurally generated sandbox universe where every tile counts. You take command of a fully customizable starship and chart your own course—whether that means mapping out uncharted systems, ambushing cargo convoys as a pirate or forging an alliance with a galactic military faction. True to its name, nothing is off limits and every playthrough feels fresh thanks to different universe seeds.
Combat and construction alike are built around a tile-based system: you can blast enemy hulls apart tile by tile, reinforce your own ship with extra armor or weld on new weapon systems. Newtonian physics add depth to encounters—a drifting wreck can be tractor-beamed into an opponent, or you can use momentum to ram hostile vessels. When you’re not in battle, hop from station to station to trade resources, manufacture advanced components in specialty labs or commission entirely new ships from scratch.
Space Impossible supports both single-player and multiplayer (LAN or Internet) and runs on Windows, Mac and Linux. The developers continue to deliver free updates, with numerous alpha builds already out and more betas on the way. You can download Space Impossible now and embark on the ultimate tile-by-tile space adventure.
