Our take on Space Impossible

The likely bounce point is the tile system: combat involves destructible and changeable ship parts rather than only weapon selection. Players who do not want construction, upgrades, trading, and manufacturing may lose interest when these systems become part of their spacefaring options.

What is Space Impossible?

Space Impossible is a space sandbox where players pilot fully destructible ships through procedurally generated star systems.

Objects are built from tiles that can be destroyed, created, or changed, making ship design and combat tactical. Players can explore unknown systems, fight hostile aliens and space navies, attack trade routes as pirates, trade goods at posts, or work for the military. Ship customization includes adding engines and applying new paint colors. Manufacturing uses gathered materials and specialty labs to create ships and components or upgrade existing ones. Multiple factions have a dozen or more starships each. Single-player and multiplayer modes support LAN or Internet play, with versions for Windows, Mac, and Linux.
