Earlier this year, iD Software released the newest game in the storied Doom series, and despite negative reception to early builds of the game, the final product turned out to be the most entertaining and bad-ass shooter in years. According to the developers, the final build of the game was inspired by "Huge demons, fast movement, big fucking guns and metal" and it certainly shows. That design philosophy extends to the incredible soundtrack that goes a long way towards selling the whole aesthetic. Bringing back the talent of Australian composer Mick Gordon, who also did the soundtrack for the excellent Wolfenstein: The New Order and season one of Microsoft's rebooted Killer Instinct, Doom's soundtrack, officially (finally) released yesterday. It's over 2 hours of grooving metallic riffs and pounding industrial/electronic elements blended together so seamlessly you'll wonder why it hasn't ever been done this well before.
