The game was a literary masterpiece with an incredibly original story. So it was with great surprise to find out that Bioshock, the spiritual successor to the System Shock universe was not going to include any form of multiplayer CO-OP component. You would think that the developers would have included it based on the critical success of System Shock 2. But alas they didn’t and we were forced to drudge through Rapture in a solo capacity. I read recently that Bioshock had just won 11 awards for various things, interesting but did it really deserve them, there’s practically zero re-playability in the game. System Shock 2 on the other hand has mountains of replayability. If they had made System Shock 3 or even re-made System Shock 2 I’m sure it would have been even more acclaimed.
