Celestial Impact is a team based multiplayer first person shooter (FPS) for PC taking place on various asteroids floating in space. But Celestial Impact is not your average team based multiplayer FPS. Celestial Impact differs from other multiplayer FPS in that the whole landscape is destructible in any direction, each impact on the landscape affecting it differently depending on the weapon used. But it is not limited to destruction; the players will also have the ability to add terrain to the landscape in the middle of combat using a special tool. So as the teams are battling, the landscape receives vast changes opening up for various tactical approaches each team can use.
Each landscape (map) is a sphere-like asteroid with gravity pointing towards the center of the asteroid. This means that players can take round trips around the asteroid assaulting the enemy from any direction. Since the landscape is fully destructible, players could even approach from underneath by digging tunnels through the asteroid.
