So, new planet zoo 2 modding controversy Almost all new species mods for Planet Zoo were created for a modloader called ACSE, which adds easy integration for all new content into the game, and ensures that there aren't compatibility issues between mods using ACSE. The main core modders for Planet Zoo are now slowly working on ACSE for Planet Zoo 2, and so aren't making any mods for it until ACSE makes mod development easier. However, that has left open that space for slop mods to appear in hordes. Already there is a vibecoded slop mod adding a bottlenose dolphin to the game, but it apparently just puts a bunch of hooks into a bunch of parts of the code that can corrupt the game, as well as uses a .exe file which should never be used for modding Planet Zoo. All the major modders are calling for folks to not install these slop mods and to wait for human-made mods for ACSE to be developed.
