Experience intense zero gravity combat and complete freedom of movement in this multiplayer first-person shooter set in near-Earth space 40 years from now.
Use your rocket pack to fly freely through space and then land on any surface. Engage your enemies in furious firefights, or ambush them from unexpected angles.
Join your friends in action-packed 32 player battles fighting to control hollowed-out asteroids, huge fragments of Moon rock and the ruined remains of the International Space Station.
Familiar and intuitive FPS controls let you take full advantage of the zero gravity environments while astonishing graphics and advanced lighting effects immerse you in the cold reality of combat in space.
