Mixing in old school first person shooter (FPS) elements with modern, upgrade, RPG-like paths, DOOM is a rewarding experience. The graphics are fine and detailed even on the "lower" console version I bought and played. Runs great, simply put, no weird redrawing of the environment or stutters in the motion sequences. Controls are tight, feel great, and let you run headlong into a pack of demons and still be nimble enough to get some aimed shots off. Glory kills never got old for me and do serve their purpose to refill health, ammo, and even armor supplies at times. The upgrade system for DoomGuy (your character) , armor, runes, and weapons is deep, especially for a FPS. The levels are huge, but not unnecessarily so, as the way forward is more often than not clearly marked by various outlines and color indicators, but not obtrusively, either. Secret rooms and areas are DOOM staples, and they're all over the place here. They're very organic to the gameplay experience, as exploring those up can earn weapon upgrade tokens and the like. Exploration of the levels fits like a glove into the gameplay. Easter eggs abound, too, with references to classic Bethesda games and older id games and a lot of things in-between. The enemy AI is a bit lackluster at times, but they're not totally silly or dumb to me. Enemies do swarm in on you in classic Doom fashion, and that's a good thing. They have pretty solid aim too, so standing like a statue is ill-advised. Audio and sound effects are good for the most part. The soundtrack is a treat, the best parts being the re-working of various tracks from the original Doom into more modern, perhaps even "industrial" versions. Some weapon effects like grenades lacked the "thump" they should have, though. I can't believe I'm saying this, but even the lore and "story" have some interesting elements, especially how id approaches your introduction to DoomGuy and his role in this game in the first place. It's not over the top operatic, it just seems to fit. While people play this game to shoot demons, the few "story" bits in the game are well done. Haven't played multiplayer at all, so can't comment. Dabbled with SnapMap some, but not enough to create full-blown maps and levels. SnapMap seems like a robust level maker with relatively intuitive setups for most things that lets people build single-player, co-op, and multiplayer levels, though. Those who are Knee Deep in the Doom mod and .wad scene will find it lacking, though. Still, there are worse game level creation tools out there, and if SnapMap motivates a few future game devs it's more than a worthy addition. More games should have mod tools, period. To be honest, I'm fine just playing the single-player campaign and feel it's worth full price to me. Thumbs up, very fun game, hope to see more (ahem...Quake maybe??)
