The Incendiary Grenade is a type of projectile weapon featured in Dead Island, made from chemicals such as Potassium Chlorate. When thrown, it explodes after several seconds and spreads fire around the immediate area of landing. Unlike the Grenade, the Incendiary Grenade does no fragmentation damage to objects around it, but sends out a blast of heat and fire that will cause the surroundings to be cover in flames and inflict a certain amount of fire damage.
- Incendiary Grenades can be only obtained by doing the continuous quest "Bleach with a Vengeance" given to the Hero by Tavin.
- In Ryder White's Campaign DLC, Incendiary Grenades can be found in or around the B.I.D.F vehicles and by the bodies. The first Incendiary Grenades are found by the 3 vehicles where the soldiers have been killed by the Raskols, just when Emily White radios Ryder for the first time.
- It is advised not to stand too near the blast radius of the Incendiary Grenade since it might send the player flying and kill them.
- Like the Grenade, the Incendiary Grenade does not have any known blueprint that the player can use to create it.
