“Unit 00”
Created when both RUBE-ADYNE Prototype and RUBE-ADYNE MK.II are picked up. Rapidly fires bouncing lasers.
Ranked against the 229 guns in the Ammonomicon that list each stat; longer bars are better. Fire rate is the delay between shots, so lower is faster; lower reload and spread are better too. Guns with several forms or charge levels are ranked on their base figure. Stats come from the community wiki and may lag behind patches.
Rubenstein's Monster has no listed synergies — it works the same no matter what else you're carrying.
