What Is Moo Moo Mystery?
Moo Moo Mystery is a Roblox social deduction survival game developed by Blox Universe where up to twelve players face off in a 1 vs All format. Matches place innocent crew members on maps like research facilities and carnivals where a disguised killer lurks secretly among the group.
Each round assigns participants as Researchers, Security, or the Cow. Researchers gather scattered cash and evade harm, while Security uses a firearm to hunt the killer. The disguised Cow draws a knife to eliminate the entire crew before the match timer expires or defenders shoot back.
