Since there seems to be a little confusion in this thread. Here are the confirmed facts: - All weapons fall under one of three categories: - [b]Primary:[/b] Rifles (Scout, Pulse, Auto), Handcannons - [b]Special:[/b] Shotguns, Fusion Rifles, Snipers - [b]Heavy:[/b] HMGs and Rockets - You can carry multiple weapons in your inventory, but you can only equip three at a time. One from each category. - Ammo availability and rarity varies from weapon slot to weapon slot. - As you defeat enemy combatants, they drop color-coded ammo drops that correspond to the three weapon slots.
