+1. I just finished that mod and it was really good. The middle map had some lighting problems (although I could give the maker the benefit of the doubt and assume he was trying to induce snow blindness rather than over expose the lighting). I played on Average difficulty and it was a bit of a challenge. The AI tends to be really tough (those guys know how to hide really well). And the eye candy was awesome.
Anyone know if there are similar mods out for Crysis?
Heh.. There are so many mods out for Crysis, you won't even know where to begin.

Seriously, some of these mod teams need to start their own studios. Such as the guys who did the mechwarrior mod.
Many of the mods are simply custom maps.
There are "modular" mods, and you can combine them to make different experiences.
For instance, there is a "natural" mod which makes bullet damage and other things more life like, as well as beefs up the AI of enemies. You could install that. Then you could start installing custom maps and levels.
This is the real beauty of CryEngine and the sandbox. Can't wait until CE3 drops and we get the editor. We'll be able to start making levels and burning them to disc to play on our consoles.
