My idea with Operation Arrowhead is custom armories. Why? For one reason in a survival custom map (survival in chernogorsk against massive waves of enemies) that i play with my friends I want to add an armory at the spawn that has only a few various smaller weapons such as an MP5A5 or PDW, and a smaller supply of ammo than default. (there are other armories with bigger weapons around the city)For another instance, suppose somebody wanted to have armories with things like rifles but just not be able to use things like MK16 EGLM because the grenade launcher could be to powerfull for the given scenario, especially the AA-12's explosive shells. For a THIRD instance. A map maker could be making a sniper level and want to allow the player to use whatever sniper rifle they wish except for the highest calibur ones like the AS50.This could allow many more possibilities in terms of restrictions and extra power.
