Equipment
Medical Crate
Ammo Boxes
HMG
RPG
-Medkits Medical crates can be chosen as a piece of equipment. They are placeable like blocks, and dispense X amount of health, possibly 500 to 1000 before running out. Once they run out they do not disappear, but stay until the block below them is broken. Empty boxes can be refilled by someone who has a medical box themselves. This feature is to give feeling to them, such as the excitement to stumble upon one only to be dismayed and find it is empty. Enemies can also use Medical boxes.
-Ammo Boxes Same as Medical crates except they dispense Ammo not Health
-HMG The heavy machine gun is a piece of equipment unlocked after X points have been achieved. When a player equips the weapon it functions as shown in this video.

Any player can use it, however the person who placed it can kick someone else off of it by using it. It is destroyed by the RPG or having the block underneath destroyed.
-RPG The RPG is unlocked after X points are scored, and functions as seen in this video.

Equipping Items
Upon entering the game, instead of chosing your weapons, you would see a screen like this:

All equipment is listed, and you click on only 1 primary, then the rest is up to you. Certain measures could be put in place however to prevent people from using only grenades. There is also a "clear inventory" button.
To change equipment, instead of suiciding you must return to the tent. By pressing Q the equipment screen opens again and you have the option to chose new weapons, or be able to chose something you unlocked.
I can't think of any other supplies at the moment, maybe binoculars or a radio which would allow you to mark out location for mortars if Ben adds them, or something like satchel charges.
