"This tier list is based off of DPS, max damage potential per magazine, and the effective combat range of each weapon. Effective range is an important factor, as close-range weapons such as Shotguns perform better versus Bugs, but worse versus Bots.

vs Illuminate Tier List: When curating the list, we consider various factors, such as the weapon’s ability to handle swarms of Voteless, effectively eliminate Overseers, and quickly burn through a Harvester’s shields."
