"Expanding beyond the pistol and Grabber, players can also utilize various abandoned UAC tools and weapons remaining from the battles that transpired during Doom 3, and they can also thoroughly enjoy the inclusion of perhaps Doom’s most celebrated weapon: the double barrel shotgun. Though slower to reload than the pump-action model, the double barrel shotgun delivers a massive punch when used up close and can dispatch pretty much anything foolish enough to enter its blast range. Then there’s The Artifact, an odd find uncovered on the red planet, and the very reason why your team came to Mars. UAC archaeologists believe it to be tied in some way to 3 demons that pursue it relentlessly, and it’s your job to unlock the secrets hidden within it while it’s in your possession, secrets that can enable its bearer to perform extraordinary things."
