Mutant! A Project Arrhythmia Boss Fight!

[@beyond1973]

You should try doing the entire Black Heart Project Arrhythmia series! Its all made by ol666 and it does have A new dawn (Jestar Hearts first appearance) and Funk Hole (Perry/Predator) plus a lot of really good levels.

OMFG U PLAYED THE ULTIMATE BOSSRUSH!!!!!!1111!1!!1!1!1!1!

[@nooneinparticularofficial]

Mutant is not "the ultimate bossrush". It is one of the best levels on the workshop, but it's not "the ultimate bossrush". Song of storms by That1guy is "the ultimate bossrush" cuz it has 18 bosses (i think). Let me repeat that... * inhales *
18. BOSSES.
You gotta admit that's nuts.

@@nooneinparticularofficial I prefer ol666's version of song of storms
