This is a very versatile weapon, and its only real weakness is its range. The Combat Shotgun is the first weapon you get in Doom Eternal, and as such, it is your bread and butter. These are the best mods for each weapon in Doom Eternal. Of course, weapon mods come down to personal preference, but some mods outshine their counterparts by enhancing the functionality of a weapon or covering its weaknesses in a certain way. Each weapon can be upgraded with two weapon mods, but with upgrade bots being far and few in between throughout the campaign, it’s important to choose the best mod for every weapon when presented with the choice. The many weapons of Doom Eternal feature several weapon mods that drastically change their function, making them suitable for a variety of situations.
