I took Warhammer 40,000: Boltgun for a spin today, and wow - what a blast from the past!
I played the absolute heck out of Doom, Quake, Heretic, and all of those 1990's FPS shooters, and this game is a loving throwback to that time & place.
The piles of gibs everywhere as you blast your way through Chaos Marines & Heretics are simply glorious nonsense.
