Shotgun-O-Rama!

"If all you had was a shotgun... how far would you go for it?"

Shotgun-O-Rama condenses an entire mod's worth of weaponry into a single weapon! Hope you love the doom shotgun as much as I do, because now it's your only chance of survival against the hordes of your enemies. Fear not, its many modifications include pinpoint Slug shots, shrapnel, arcing grenades and more! It's all you have, but it's all you will need.

You also have access to the Sacrificer, which lets you summon extra ammo at the cost of health. It may also grant you extra damage for a short time, at a cost...

Use your Reload key to cycle through secondary fire modes.
Altfire fires them (providing you have acquired it).
Zoom key lets you hit enemies with the butt of the shotgun.

Made with GZDoom 4.9.0, tested with GZDoom and LZDoom 3.87.
Compatible with any ZDoom-derived port and Doom IWAD.
