Maybe you missed Serious Sam back in 2001? It's a fun, frantic fantasy FPS. A headlong charge in through one end of Thebes and blasting out the other. Into space. The remake loses none of the lunacy. HD is still all about gunning down swarming enemies. Harpies that shoot ice, zombies that spray fireballs, swarms of exploding frogs, electric piranhas, bio-mechs that stomp around and shoot rockets and lasers. The Headless Kamikaze, a roaring, sprinting corpse with two ticking bombs and a personal space problem, appears in every ensemble of enemies throughout the game.
