Which Space Game(FPS. Sci-Fi)

I'm looking for a game in Space, somewhat like Dead Space

Sci-Fi or FPS

I remember seeing a game video out here but my browser crashed and cudnt recover it.

I remember the Player can fly around have spaceships and the engine has a special no gravity feature, but cannot remember the name.

And please suggest me any similar games to if you guys can, kinda bored with the same old stuff like NFS dunno any other better racing game either.(Not much into gaming u prolly guessed by now)

try Mass Effect.junaid15

System Shock 2.
