ZeroG is a space shooter with slightly more realistic physics than your average!
If you're moving you will carry on moving in that direction until you accelerate in the opposite! There is no top speed so if you're closing in on an object remember to leave enough time to decelerate or you'll just go straight past... or possibly collide.
Talking of collisions, the damage recieved from them, both from bullets and other ships, is related to their relative velocities, so bear that in mind!
WASD, Shift and Space controls your acceleration, Q and E roll your ship, right click turns your ship, and left click fires. Esc pauses the game.
