BioShock fans will probably want to pull the seat up close to the monitor because the Siren Alley trailer is like a floodgate of gaming goodness when it comes to showcasing new environments, weapons and enemies in BioShock 2.

Some fans probably already got a sneak-peek at a lot of the footage in GT TV’s BioShock 2 special. Nevertheless, for everyone else who missed out on some of the neat weapons that will be at the player’s disposal and some of the dank and watery decrepit environments that will be traversable in this epic-sized sequel, then here’s your chance.

BioShock 2 will feature more plasmids, new bosses and a brand new multiplayer mode that should add a good measure of replay value to the game. You can check out the new trailer for the game below or visit the Official Website for further information.
