Rimworld Alpha Animals Tier List May 2026

Why D-Tier: An indestructible, non-aggressive gelatinous cube that slowly duplicates every 3 days. It cannot be killed, only moved. It eats no food, but it blocks doors and pathing. If you don't freeze it or delete it via dev mode, it will eventually fill your entire map with useless, moving garbage. A novelty for masochists.


If you are installing Alpha Animals for the first time today, ignore the Gallatross. Ignore the Mimes. Go find an Aerofleet.

They are the safest, most reliable, most broken economic animal in the entire mod. With a stable of 10 Aerofleets, you will never need to mine for chemfuel again. You will power your generators, your mortars, and your flamethrowers. You will sell the excess chemfuel to buy components. You will expand while the tribals freeze in the dark.

Just don't let them die near your hospital.


Have a different opinion? Did a Nightling save your ice sheet run? Or did a Fractal destroy your 500-hour save file? The Rim is vast, and the genes are always mutating. Stay paranoid, stay fed, and never trust the deer.
