How's the level design? Please tell me it isn't like crysis 2 and more like Crysis 1 / warhead.
From what I played through, which was just the first hour or so, it's much more open. If you're expecting C1/WH sandbox freedom though, you'll be disappointed. If you want more freedom than Crysis 2 gave though, you'll get that. Levels are a lot bigger, less linear and it does have a similar feel to C1/WH where you can approach each area differently to get to the end goal.
The game is a lot better than Crysis 2, visually and gameplay wise, I can say that 100%. The game is fun and worth getting imo. The bow gameplay is awesome and it has different bolts you can use; explosive, shocking, etc. NPC AI is intelligent and well done like the first Crysis as well. I agree with the above that the alien areas of all the Crysis games have been crap and feel like a step down from the human AI. I'm sure at some point in C3 you get to aliens again...
The first area when you start playing is just killer. Looks amazing and immediately I was thinking, shit my computer is getting hammered, 30-35FPS. After that first area it improves quite a bit though and frames go up. Crysis 3 has dethroned Crysis 1/Warhead in the visual department as well, big time. The NPC modelling is the best I have ever seen and the lighting/shadows are just incredible.
