IGN have a new video up (
Part 3.)
New information.
1. Jump will be grounded in reality (you can't shoot and jump at the same time).
2. Audio Occlusions (Different enviroments will sound differently, thicker walls etc will make the sound, sound differently).
3. You can see alot of flies near the light sources in the ally. (nice touch, I havent noticed before).
4. More weather based gameplay than just 'lightning'.
5. Hit respond system (motion captures and physics impulses will blend to create unique animations).
Enjoy!
