Finaly I've managed to port out the Proxy mine layer from the Chaos game without having to use the 280Mb chaos mutator lol, it's now a seperate gun away from Chaos.

This gun puts out "Proxy Mines", little yellow smiling bombs, they constantly jump about, hunt and chatter amoungst themselves lol, they are actually bots, so unlike spiders they have AI, they will protect you and go hunt for you, but unlike spiders etc, when you die they don't, they will either go to sleep, explode or go join another group belonging to someone else, so you could have a tribe of them lol, they are very touchy, if you upset them by running over them for example, they will call you a trator and hunt you instead hehe
