If the immunity cvar (goomba_immunity) is set to 1, you can use those commands (in the console): - goomba_status print your actual immunity setting in the console. - goomba_toggle toggle your immunity setting. - goomba_on disable immunity. - goomba_off enable immunity. An immune player can't be stomped but also can't stomp. Immunity changes take effect on respawn or when you touch a resupply locker (TF2).
