Go on, I'll wait.
Anyway, this is a weapon mod that is quite different. Look at the below screens.



Yes, those are the same weapons. If you don't know what I mean, check the ammo types. If you still don't get it, doesn't it strike you odd that the regular DOOM supershotgun uses clips? (In actuality, none of those use clips. I just did those screen with that for the sake of showing off.

Now, you may be wondering how all of those are the same weapons. Take a look at the top-left corner. In the COP Derringer (actually 4shot in the wad) screenshot, there's an M. In the Quad Shotgun screenshot (room cleaner) there's a V. And in the SSG screenshot, nothing. I'll leave it to you to figure out what that means.
In the meantime, you can control the letter (limited to M, V, and a blank) that appears there by pressing the key that is bound to them, which is defaulted to Z, C, and X, respectively.
Now, if you haven't figured it out, the M, V, and blank refer to what gun you have selected. Blank is always the standard DOOM version of the gun. There's no standard to the M or V, though.
Here's a list of the guns:
Fist
M: Fast Feet - Super powerful feet allowing you to burst through a level in a few seconds, if you keep control of course.
V: Flying Knee - Unleash your beat-em-up roots with a double jump! Plus a knee instead of a fist.
Chainsaw
M: Incredible Ripping Rubber Chainsaw - It's as awesome as it sounds. Remember the throwable chainsaw from Deathz0r's awesome OMGWEAPS.wad? This is it, except with bouncing. Causes you to lose the Chainsaw after use.
V: Scattergun - A monochrome gun of 1-bit destruction. It shoots a ball that explodes into many small ones. 5 clips per shot.
Pistol
M: Singleshot - 4shot except without rape and rapid fire. Uses 5 clips.
V: Rapid Pistol - Pistol that's less accurate but with less recoil allowing faster shooting. 1 clip per shot. Probally going to be replaced.
Shotgun
M: Sniper Rifle - A super-accurate gun. When you put it over a target, there's a beep. 1 shell, 5 clips.
V: Auto Shotgun - Fast version of the shotgun, reloads after 6 shots. 1 shell per shot.
SSG
M: 4shot - Think Auto Shotgun, but more random with the number of actual shots within a burst and also reload after only 4 shots. 2 shells per shot.
V: Room Cleaner - Rapid SSG with a long cool down. 2 shells per shot.
Chaingun
M: Uzi - Chaingun on crack and long cool down. 2 clips per burst.
V: Trishot - Yep, three (four if you count my SSG nickname) guns that end in shot. Oh well. Three rotating barrels allow quick shotgun-ish firing. 1 shells and 3 clips per burst.
Rocket Launcher
M: Archflame - Six-shot burst and then an explosion! 3 cells and 1 rocket per shot.
V: Deathzone Launcher - The Archflame's bigger brother, except without the burst. 5 rockets per shot.
Plasma Gun
M: Proton Launcher - Cannon might have been better. Meh. Fires a stream of weak-but-fast plamsa that home in a bit. 1 cell per burst.
V: Railgun - That poweful ripping weapon, you knew it would be in here. This one is multi-colored, and won't let you shoot unless you point at something, thanks to that computer terminal on the side. 2 cells per shot.
And for the sake of it
To-do list:
-MV modes for the BFG9k. Almost done here.
-Maybe make the MV counter in a more LCD-display-ish.
-Various other touch-ups.
And here's the download link:
http://www.sendspace.com/file/a8mpdc - Beta 1.7 (Plasma Gun added.)
http://www.sendspace.com/file/0uscnw - Beta 1.6 (Chainsaw added.)
http://www.sendspace.com/file/ng9i2u - Beta 1.5 (Fist and Rocket Launcher added. Plus tweaking!)
http://www.sendspace.com/file/qgbdpz - Beta 1.4 (Pistol and Chaingun added)
http://www.sendspace.com/file/ijtbvb - Beta 1.3 (previous versions where among me and a friend of mine)
The main reason I'm releasing a beta of it now with only two weapons done is because I want to see if anyone would like to request something or donate something for the cause.
Plus I need people to help me balance the weapons, as I usually make weapons too powerful.
