Co-Op upside down shooter, Inversion, has been released for Windows and is available to download via Steam. The two player co-op game features a campaign with a gravity defying gimmick that we thought was "a solid combat experience" but suffered from "a bland story and stock characters."
The PC version of the game is listed at $39.99 and feature the same online co-op experience as its console counterpart. The game also fully supports a gamepad for maximum enjoyment.
