E3 2015 doesn't kick off until tomorrow but Bethesda Softworks has treated us to an early look at the gameplay for the upcoming DOOM video game. The Maryland-based developer, known for their popular titles like Fallout and The Elder Scrolls, brings back the classic series with some incredible visuals and updated features. The iconic first-person shooter first debuted back in 1993 and though a number of expansion packs and spin-offs have kept fans busy for a while, we haven't seen a follow-up since Doom 3 in 2004. Taking place on mars, players will take on an army of monsters using a barrage of weapons. DOOM is expected to release early next year. Take a look at the clip below and be warned, it's quite gory.
