Doom 4 was shown behind looked doors at QuakeCon 2014 on July 17, 2014. Rumors from those lucky enough to see the preview of the game teased us with melee combat, finishing moves and decapitation of enemies.
While we still haven't found any leaked footage from the show, modder TheOneButcher from Cryengine forums has created a SciFi scene in Cryengine 4 that has a graphical style remenissant to Doom 3, but with updated graphics, curtesy of CryEngine 3. Might this be a hint of what Doom 4 coul'd look like? We think so!
