Cow

You start in a human disguise. The role card tells you that you are secretly a cow, to act natural, and to kill everyone. A playthrough's how-to text called this killer Mumu. You cannot damage anyone in human form. Press 1 on desktop to transform and put the knife in your mouth. Press E to throw. Close melee is the other attack. Crouch with C. If Security shoots you, the crew wins immediately. Surviving until the timer with crew still alive is a Researcher win, not yours.

The lobby shows role percentages. Consecutive rounds as a Researcher raise the chance of a rarer role. The 2x Cow Chance pass costs 249 Robux and doubles your Cow chance. It does not guarantee the role. Public servers put one Cow in a match of up to 12.

Isolate players who leave the group for Cash or event chests. After a kill nobody saw, press 1 and walk away. When Security dies, Researchers run to the dropped gun. Wait off the doorway and stop them before they pick it up. Do not chase a stack that is standing on Security. Knife throws need a clear line; Arcade clutter eats them. Missed throws have a short recovery.
