Just wondering what you guys think are some of the best Half Life 2 mods, I am waiting for the co-op made by Sven to be released...

the sven co-op sounds really cool, it'll be fun.

its really awesome... (i didnt get a chance to play around cuz my new comp doesnt have internet)
wut u do is... u drop ppl on the floor u put them in funny positions... u can put them in a bath tub and add wheels to it and u can squirt blood on em put em on a chair and make it fly.... all that stuff
