Haven't had this much fun with a FPS since Half Life 2
I am a fairly new 360 owner so most of the games still amaze me graphically. This game is no exception. It backs up amazing graphics with excellent story, sound, voice-acting, and gameplay. It is everything we have come to expect from a next-gen game.
The environment in the game does an excellent job of immersing you into the city of Rapture. From the look and sounds of the city to the physical part of it. Hit something with your wrench and it dents, cracks, or breaks like it should.
Even if you can't afford to rent this game, anyone who even remotely likes first person shooter games should rent this.
