Non-Inventory Items

Gas Tank
A good crowd control item, use it to wipe out entire packs of zombies. Beware though as the flames can sometimes allow shamble's to turn into runners! The only downside is that in order to avoid taking explosive damage from the blast, players have to use a firearm to ignite the tank. If not, hitting it with a melee weapon will potentially kill the player.

FEMA Duffel Bag
A zone repair item only available in Survival maps. FEMA Duffel Bags are found in special boxes marked with yellow glow sticks. In order to use it, the player must bring the bag to a zone that has less than 90% health left. The bag will disappear and grant a 25% health boost to any sufficiently damaged zone that it is dropped in. The FEMA Duffel Bag's only function is to repair zones.

First-aid box
A somewhat bulkier version of the first-aid kit, this item is only available in Survival maps. The first-aid box holds 150% of a player's health - enough for an entire team, if it is rationed properly. Unfortunately, the first-aid box is often stashed in places far from the player's reach, usually near the zombie spawning areas. This makes it difficult to retrieve, especially during an ongoing horde attack. It is advised to retrieve the first-aid box AFTER a horde attack to avoid complications and loss of lives.
