Recently I posted the front cover of PCZone June 2006 which on our forums.
There has been a little debate over whether the water featured on the front cover was in game, or whether it was added post process for the magazine cover.

It has been confirmed by Chris Kline of Irrational that the water is indeed part of the game, and was not added for tha magazine.
Wow!

Additionally, another member of the Bioshock team has confirmed that Bioshock is using a heavily modified version of Unreal 2.5 as its engine, and not Unreal 3.0 as reported by PC Zone.
