This is my dehacked 3.0 patch that give you and your monsters new arms.
You must have DOOM II (It doesn't matter which version is) and Dehacked 3.0
These are weapon replacements:
        Weapon/monster      changes
You
        Pistol:             Name: Pistol Model 1000
                            Not many changes, but speed doubles.
        Shotgun:            None
        Quad Shotgun:       None
        Chaingun (Vulcan):  Name: Gauss gun (In descent II)
                            Doubles the damage, but Doubles the ammo usage.
        Rocket Lanucher:    Name: Omega gun (In descent II)
                            Fires a large amount of gray Baron fireballs
                            but it's a short range weapon.  (Limit-ranged
                            Projectiles).
        Plasma cannon:      Not many changes, but Fires green instead of
                            Blue, and fires faster, and no recharging
                            required after firing.
        BFG 9000:           Name: Phoenix gun.  Fires at the speed of
                            Normal plasma gun, and damages 3x times
                            the plasma bullet.  However, it
                            Doubles the ammo usage again.
