Well, my main one is maybe going to be in DSL 3.0, lol :P (Go on, take a guess at who it is :P)
Warhead..From the people who made razor
I'd go for Snake
I would like to see a better Biohazard.
In the DSL 3.0 preview thread, that was one of the things Click said he was going to work on. I'm excited for the new Typhoon 2! The old one was a pile of sh*t.
