• The Coolio TC will have all new weapons.
• Here's what I've drawn so far:

The Pistols replace the Pistol.

Rifle

The Rifle replaces the Shotgun.

Plasma Generator

The Plasma Generator replaces the Chaingun. 

Rocket Launcher

It's a Rocket Launcher, what else do you want to know?

Hand Grenade

The Hand Grenade Replaces the Pipebomb, but you have to detonate youself because I don't know how to get rid of the detonator.

C4 Bomb

The C4 Bomb replaces the Tripmine.
