While developer Irrational Games didn't reveal their next game at E3 2010 last week the team behind the original BioShock is letting its fans take another look at the original pitch for their best known title. The developer's official web site posted the first half of their pitch last month and now they have revealed the second half of the original Bioshock presentation.

The second half takes a look at Irrational's original ideas for the game's interface, brief descriptions of the game's enemies, a back story that's far different than the one that actually showed up and ideas for multiplayer modes that were ultimately never used.
