The good old Mighty Foot. Your quick melee has lots of knock back power and deals reasonable damage. 1st upgrade gives more knock back and air control; 2nd gives more damage and more air control.

A chainsaw design right out of Evil Dead. Replaces chainsaw (duh). Does lots of damage, and is used like dooms regular chainsaw. 1st upgrade give it a swing altfire that can hit multiple enemies; 2nd increases damage.

Duke's golden desert eagle which never made it into the release version of DNF. Starting weapon. Does good damage, but is wildly inaccurate at first. 1st Upgrade increases accuracy from bad to good; 2nd allows for dual wield (with synthfire).

Assault rifle with an american flag on it. Replaces chaingun. This one was also in a DNF trailer. Is somewhat inaccurate, fires at a decent speed and does decent damage. 1st upgrade give it a scope, which allows near perfect accuracy while zoomed; 2nd gives a grenade launcher which uses 35 rifle bullets.

The shotgun. Replaces shotgun. You should be familiar with what this does.

The minigun cannon. Replaces supershotgun. When a chaingun cannon just isn't enough, this is the solution. Fires fast and has very high DPS. However it eats through ammo like there's no tomorrow. 1st upgrade increases fire rate; 2nd increases damage per bullet.

The RPG. Replaces Rocket Launcher. This baby does lots of damage and fires at a decent speed too. The downside? Killing yourself with it. 1st upgrade increases projectile speed; 2nd upgrade allows you to fire 3 rockets at once (altfire, uses 3 rockets).

The Plasma Gun. Replaces plasma rifle. This has placeholder behavior, so expect this to change. Shoots a powerful plasma explosive with a small blast radius. Don't stand in the explosion. 1st upgrade increases projectile speed, 2nd negatges the explosion damage to duke.
