There’s something brewing under London and the creators of the epic Diablo series are the ones to blame. Something like an FPS MMO RPG (OMG, TLA’s! WTF?), Hellgate: London might just bring a little undead life to the first-person action scene. Hellgate: London is set in a near-future post-apocalyptic London setting where demons have opened portals to the earth. The demons are winning, but the last vestiges of humanity have banded together and are fighting back. Using London’s underground network of tunnels, a literal underground rebellion is making small headway in fighting back the demon invasion.
