DOOM(2016) into Fallout 4

[Quhark]

What would be lore breaking, overpowered and pretty cool?

Weapons and Armour (or possibly Power Armour) from the new DOOM game. If I were to compare, we already got some weapons that are similar to those in DOOM like: shotgun(auto), super shotgun, plasma pistol, minigun, rocket launcher. I've seen mods like a .50 heavy machine gun without reload or a rail gun(gauss rifle), even BFG could be similar to the fat man but lobs plasma instead. The armour would grant a great speed boost and weight capacity(also boost melee damage).

 

This would probably make the game too easy but it would be hella fun running around and punching supermutants into gore(in my opinion)
