Doom 2 is more than just Doom these days. Some modern levels for the 90s classic FPS feature thousands of enemies, fiendish traps and difficulty beyond anything Id Software dreamt of. Eviternity, released yesterday, runs the gamut. It’s a 32-level campaign split up into six episodes each with a fresh look and some new monsters. You’ll start out in gloomy gothic tunnels, plinking away at zombies with a pistol. By the end, you’ll be screaming through the vast halls of heaven itself, cutting through ungodly-huge swarms of demons with BFG in hand. It’s rather brill.
