The first-person shooter genre could be in for a very big wake-up call when Crysis debuts. The sophomore effort from Germany's Crytek is one of the biggest games on the horizon, thanks to the impressive screen shots released thus far and the reputation the company has earned from the superb Far Cry. As we covered in our last preview, the designers at Crytek want to create a game with a story that's as flexible and advanced as the cutting-edge graphics engine that powers it. In other words, you'll be able to go through the game in different ways instead of experiencing a rigidly linear storyline like that found in so many other first-person shooter campaigns. However, another goal of the design team is to create a believable and dynamic environment to battle in. The graphics in Crysis aren't just there for eye candy, as the game's physics engine means that everything behaves like it should, even when the conditions change drastically. Please note: this preview story may contain minor spoilers of some of the story elements in Crysis.
