When killed models change a bit, for example, their eyes will close. Also, when killed, the bodies fall into unique positions depending on how they fall. Another nice effect is the fact that bullet holes show up and stay on the walls. During snow missions, teammates masks fog up, and there breath can be seen. Redstorm has focused on the details and added a lot of neat little things like this to keep you wanting more.

Redstorm has added a few new features, players now have the ability to duck and crawl at the same time, and also have the ability to peek around corners as to not get your nads shot off. This is an especially neat tool, as you can gloat to your friends while watching previous battles over and over making them feel like the smallest turd upon your boots. Redstorm's sound department is most excellent.
