Invulnerability



The invulnerability is a powerup that makes the player immortal for 30 seconds, during which the screen also turns black and white and in negative. It does not protect from telefrags. It looks like a green sphere with a grinning head inside.

The invulnerability can also be activated with the cheat code idbeholdv.

In deathmatch, invulnerabilities re-appear every 5 minutes.
