If you play first-person shooters on your PC, the very mention of the original Crysis brings to mind lush jungle beauty brought to life by a graphics engine so impressive and flexible that it remains the visual benchmark to which all other PC games are held. Crysis 2 does an admirable job of living up to the original's reputation of sheer technical prowess, though the visuals aren't as immediately impressive as you may expect. But this sequel still looks great and plays that way too. The jungle is now of the urban variety--New York City to be precise. You make your way through office buildings, across crumbling bridges, and around broad city squares, where robotic aliens infest hallways and swarm across rooftops. Large environments give you room to maneuver and grant you freedom to approach battle in a number of ways, which makes Crysis 2 a great alternative to the plethora of first-person shooters that usher you down corridors on your way to the next action movie set piece.
