TH-Grenade is a special variant of the basic Grenade available only in Challenge Mode.
This grenade behaves exactly like the Mutation Grenade, dealing massive damage against zombies and does not affect human players. It shares explosion sound with Mutation Grenade.
- Available in all CrossFire versions.
- Despite having a proper Bag Icon, TH-Grenade lacks a Thrown Icon so it won't show up in players' bag when switching with AI Bag Switch.
- Strangely enough, this grenade has killmark icon too. Probably it was planned to be an obtainable grenade and usable outside Challenge Mode.
