Weaponry in Firefall are split into 2 main categories: Primary and Secondary. Primary Weapons can only be used by the specific type of Battleframe it is assigned to, including Advanced Battleframes from that archetype(e.g. Rhino using Dreadnaught's HMG) , if available, and are limited on ammunition. Secondary Weapons, on the other hand, can be used with any Battleframe and have infinite ammo.
