One of the most anticipated games of the summer, BioShock, is finally out on the Xbox 360 (PC version is coming on a few days) and first batch of reviews are in as well. And judging from those reviews, the game delivers on all fronts and is a must have for any FPS fan.

IGN (97/100) “BioShock stands as a monolithic example of the convergence of entertaining gameplay and an irresistibly sinister, engrossing storyline that encompasses a host of multifaceted characters. This is an essential gaming experience.”

Eurogamer (100/100) “BioShock is the ultimate rarity: not only does it live up to its lofty promise, but exceeds it through simple, old fashioned talent and imagination – not to mention verve, style,class, wit, and sheer bloody-minded ambition.”

1UP (100/100) “Taken as a whole, as an experience that’s richly and utterly complete, and one that engages the player in a constant dialogue, BioShock is virtually unassailable.”

GameSpy (100/100) ” Put simply,BioShock is an unparalleled achievement. No other game comes even remotely close to it in terms of raw emotional connection. It may still be too early to name a Game of the Year, but after experiencing BioShock in all of its haunting artistic glory, every other game will have to try that much harder to even be considered as a candidate.”
