I think the first thing you will see are the hands, that why so messed up?
weeel, it uses human_male animations, what are farcry default ones, i don't really think that is there a point of making new animations to it, but well see.
The cool part is that they can also jump to place to place like in halo reach so that gives a good effect, there are actually 2 types Skirmishers and a lot of helmet types, its morning right now but when i come back home i will compile the helmets also and make a video, or another picture.
have a good day!
