It will be a very cool wargame if we had a secondary gun, like a berreta or a glock. :)

Some people want crafting or forging where as many people oppose to this because people tend to suggest minecraft like systems. My system how ever does not induce a minecraft feel to it at all, infact it doesn't involve gathering resources from the map at all. My idea is very simplistic, kill an enemy, melt his helmet down for steel, then forge it into chiz.
Helmets are dropped from enemy corpses (This encourages people to engage in combat rather than sit back and snipe). Helmets are then brought back to your teams tent where they are converted into steele bars. Steele bars then can be put towards an item (It's more shop than forge but it's a start).
Forge items have endurance counted in lives, meaning they're gone after dying X amount of times. Forge Items switch out with the grenade slot, and they return to grenades after they run out of endurance.
Forge items can vary from each other from the slow healing voxicilium to the rapid fire of the Super Clip and even to the much requested bullet retardent Steele Block.
