Arsenal Demon takes a look at almost all of the shooters released in the last 2 decades and shows them the finger. You won't find trends here. You won't find bland modern gameplay sensibilities. What you will find is something insanely fast paced, off the walls(as you run along them), with nothing held back. And it's absolutely glorious.
If you like comparisons, it's as if Quake and Devil Daggers had a baby, and that baby went on a never-ending "haste"(meth) binge.
I's a hecc'ing good time. Play it now.
