Is Dumpster Gang on PS5?

Yes, a PS5 version has been announced. No, you cannot buy or download it yet. The month is March 2027. We found no specific day, price, or preorder link in the checked sources.

People asking whether a PS5 raccoon can join a PC friend should read the crossplay page. I am not answering that here, because the studio has not answered it, and repeating a guess on two URLs is how sites drift apart.
