MW3 Zombies Toxic Damage explained

Toxic Damage is a status effect in MW3 Zombies. You can do Toxic Damage through the Experimental Gas Tactical or the Brain Rot Ammo Mod.

Simply throw an Experimental Gas grenade into a group of MW3 Zombies and keep them in the gas in order to do as much damage as possible. If you choose to use the Brain Rot Ammo Mod, kill as many zombies as you can with the mod and those affected by the status will go around killing other zombies and then die themselves, which counts towards your Toxic Damage challenge.
