A collection of ascended user made mods of wildly varying quality, but generally tending towards being good-to-great, despite how gimmicky every single new slugcat is. Considering Rain World's.... peculiar fanbase, it could have been so much worse, even if some of it still plays and reads like bad fanfiction (mostly the spearmaster campaign).

edit: very belatedly docking a star over the insufferable sense of entitlement a substantial part of the community has developed around it; I have to agree with other reviewers who correctly argued from the start for it being detrimental to the main game, or at the very least to how it is perceived.
