For those who thinks the Zombie Grenade Kill is a bug exclusive to Zombie 4: Darkness, it's actually not. It actually can happen in any game modes that involve instant team switching (ZM1/2/3, Hidden, Bot Zombie). It can be done with most things involving grenade projectiles, HE, OICW, or non-grenades like the Plasma Gun.

Someone need to test this on SVDEX, M32 and M79.
