Want to beat the system, and other players, in DOOM? Grab a shotgun. Well, to be more exact, grab two. There’s a DOOM exploit that makes the most of swapping between the two shotguns as quickly as possible to make everyone who isn’t you miserable.
Here’s how this DOOM exploit works. You equip one shotgun as your first weapon and another as your second. That’s it. No fancy maneuvering. Just make sure you have the right loadout. Once you’re in a match, shoot, switch weapons, shoot, switch weapons, rinse, and repeat. There’s no reloading, only constant fury.
Which means everyone is going to be testing this DOOM exploit out. It’s not like it takes too much skill to make sure you have the right equipment and good timing. It might be wise to go ahead and test it out once or twice, then avoid multiplayer until this gets fixed. It seems like it could be a real buzzkill.
