Space Run

Space Run is a real-time spaceship construction strategy game that takes the familiar tower defense formula and twists it: instead of defending a fixed position, you manage and protect a spaceship and its cargo against the dangers of deep space. You play one of the daring Space Transporters, hauling valuable shipments across hazardous space lanes.

The job sounds simple until you add dense asteroid fields crossing the lanes, heavily armed pirate starfighters out to shred your ship for its cargo, and rival Transporters competing against you. You build modules on your ship as you fly, laser turrets, missile launchers, shields, thrusters, and power generators, adapting quickly to every new situation, and flying faster boosts your reputation.

As your reputation grows, harder missions carrying more expensive cargo earn credits to unlock and upgrade new ship modules. The game offers high replay value, letting you revisit earlier missions with newly unlocked modules to finish them faster and beat your own and your friends' scores.
