Another boomer shooter like Quake, DOOM, and Dusk.
Good level design and enemy variety, great atmosphere and setting and uncommon weapons, they still fill the same needs as the usual suspects like the shotgun and rocket launcher but making them magic staffs is a nice touch. It's kinda short and there are some really noaying platform sections here and there, also the visuals are kinda weird to look at at first but you get used to them eventually.
Otherwise pretty much it's exactly what you would expect from this genre. If you like some good ol' shooters, give it a try.
