Yeah, I want to get most of the mod finalized before it's ported to GZDoom. I'm just getting sort of concerned because crouching plays an integral role, and I'm still unfamiliar with how Graf handled his implementation. Everything else should go in without a problem, however.
And here's the (hopefully) MP version, plus a modified slide attack. Now you can take down more than one enemy if they're relatively close together when you slide into them.
