"Lone Gunman" Custom Game Mode addon - Half-Payne (now with Twitch integration) mod for Half-Life

Inspired by Left 4 Dead 2 mutation, this addon adds 2 new custom gamemodes.
Lone Gunman:
- Only one weapon allowed for entire run: Desert Eagle with infinite ammo (it can shoot underwater)
- Everytime you load a map a lot of monsters spawn
- Very high tension gameplay: who will you prioritize killing first knowing that you have 7 bullets only in magazine?
Lone Gunman - Black Mesa Minute:
- Pretty much the same thing but without monster spawns
- Black Mesa Minute
