DESCRIPTION:
An M79 Grenade Launcher, based on the one the T-800 uses in the movie Terminator 2: Judgement Day.
Compared to the Rocket Launcher, it has less direct damage, slower to use, and is affected by gravity, but in return the
projectile is faster, has way more splash damage, and has a timed alternate fire.
Just don't use it at point blank range.

Wunderbar! But if you do care at all, I know a sprite sheet with a more vanilla look.

I spent hours making the sprites, and I'd like to keep as much original content, but do tell....

Osjclatchford has a sprite sheet done on Doomworld

We already have an M79 Grenade Launcher, but I find this one more accurate. The one we have will be renamed and updated once I get better sprites for it.
I find some of the sounds very loud. The volume of the explosions should be reduced to 0.7 (also they can only go up to 1.0, so setting them to 50 wouldn't do anything) and some of the weapon sounds should be reduced in the SNDINFO:

You should get a new sound for GRNTIM, instead of reusing a stock SuperShotgun sound.
Also you could give it a new ammo type, since it deals more damage than the Rocket.
