Animations: Unseen_1 (ported by fub) or JamesM
Arm convert, compile: fub
If you've got HLMV you can preview the animations, if not try both animation sets out ingame. All you have to do is rename v_c4_james (or _unseen) to v_c4, put them in your cstrike/models folder, and you're set.
I'm aware the world model is very small. If it was any bigger it wouldn't pass consistency, so you'll have to deal with it, sorry :]
