Fist - The fist basically one shots and gibs everything up to cacos; the alt-fire consumes plasma and heals anything within melee range.
Chainsaw - The primary fire is beefed up to all hell, and the altfire throws a chainsawing damn near 1-shotting barons. Powered up version makes throwable chainsaws able to bounce off walls as well.
Pistol - Fires a rail that gibs all the lower-tier enemies easily. The altifre is a simple zoom feature with 2 distances.
Shotgun - Fires powerful hitscan that gibs low-tiers; alt-fire fires an even larger spread that murders cybers in just about 5 shots.
SSG - Fires ripping plasma bolts that can bounce off walls [can easily 1-shot a cyber with the proper room] Alt-fire shoots an archvile like attack that murders whatever you're looking at without much need to aim. Powered up primary fire allows you to fire even more plasma bolts [probably 3-4x more than normal]
Chaingun - Same exact thing as the pistol, but rapid fire; alt-fire is the same as well with the 2 distance zoom function
Rocket launcher - Fires beefed up rockets, can 3 shot a cyber; Alt-fire shoots a homing rocket launcher than can also bounce off walls. Powered up primary fires a giant rocket with humungous splash damage, that also releases a hail of mancubi shots. Secondary launches a ohko lost soul.
Plasma Rifle - Shoots plasma balls that freezes enemies; alt-fire shoots floor hugging cacodemon blasts that can rip through enemies. Powered up version primary fire shoots mini bfg balls, with the alt-fire launching floor hugging mancubi shots.
BFG9000 - Shoots a bfgball on steroids that 1-shots cybers; alt-fire launchers floor hugging mancubi blasts that rip through enemies in a complete circle around you. Powered up version shoots even more bfg balls on primary fire in a circle, and streams of fire in a circle [after a brief delay of the icon of sin awakening sound] Note: I tried it with chillax, it sounded kind of cool with the icon voice changing to 'You can never defeat me'
The weapons all in all: All of the weapons are as the title described as 'over powered', but the weapons don't really have what makes op weapons fun in the first place. If you look at some other op weapon mods that were fun as hell [of course I'm going to mention Russian overkill] they showed huge explosions and some unique weapons as well. I feel for an over powered weapon mod to hold its novelty it needs to have uniquely powered weapons that makes you wanna jump into a slaughter wad and test them all out on hordes of monsters. The berserk power up makes projectiles reflect off of you, gives you an obscene amount of hp [36,000-something? empyre mentioned the exact amount in his post]. You can stack megaspheres and soulspheres, making you have enough hp to complete all of map 25 in av with just the fist and still have over 1000.
Balance - ?? / 10 - I mean its an op weapons mod y'know...
Creativity - 7 / 10 - I mean I feel like I've seen most of this implemented in some way already since they're not that advanced to begin with, the power-ups however do add an interesting twist [rocket launcher spawning a ohko lost soul.
Replay Value - 4 / 10 - I don't think I could play this more than twice max with its basic arsenal
