Aliens: Colonial Marines wasn't very well received, and with good reason - the game sucked. This was especially so for PC, where the developers had seemingly took everything that was good about the console version - and it was slim pickings there as well - and made it worse. Even the graphics seemed to take a knock, in part thanks to FPS glitches that some suffered from. Gearbox have this morning announced that they're bringing a pretty major patch to the game's PC version in the hopes of smoothing everything out. I can't imagine it'll fix the myriad of game issues, but it might just make it less "not at all playable."
