I've released the source code which you can check out here:
https://github.com/psbj/rxmod

I'm sorry I gave up on this. If I ever pick it up again or there are bugs that need hammering, it'll be updated there.

I haven't really had the chance or urge to work on the plugin during the last few weeks. Been working on other projects and by the time I'm finished I don't want to code anything else.

I know many people want to see this; I'm not abandoning this, I promise!

Charger: crouch charge uppercut
Spitter: crouch charge for invisibility and speed
Hunter: crouch charge pounce damage
Recon: crouch charge super jump
Tank: crouch charge fire punch
Hunter: turn invisible and silent while not moving
Smoker: teleport sound fx
General: fix infected select not working when you start as charger

Still getting the hunter stuff just right and I have yet to work on the tank stuff.

I've been busy with other projects so I haven't had much time to work on it in the last week or so.
