Rapid Fire, small calibre projectile weapon...
— In-Game Description
A multi-cannon is a large caliber machine gun mounted on one of your ship's hardpoints and needs assigning to a fire group before it can be used. These weapons are projectile based and use actual ammunition, which needs replenishing when depleted. Multi-cannons consume less power than energy weapons and as a result, give off less heat. These weapons generally have a longer range than their energy counterparts. They fire from a magazine of 90 shots, which automatically reloads when empty. Each multi-cannon that's been mounted, and is active, has its own pool of 2100(when full) ammunition to supply it.
Multi-cannons are available as fixed, gimbal mounted, and turreted versions.
Spent ammunition must be replenished once used. Any station is equipped with a "Re-arm" service will be able to replenish ammunition. Once docked at the station, ammunition can be purchased from the Munitions menu in the Starport Services. Each shot costs 1 CR, therefore each magazine costs 90 CR, and one increment of 100 (standard re-arm unit) is 100 CR. Example: you fire 460 rounds in a fight, your total cost will be 460 CR, 4 "units" at 100 CR each, and a prorated "unit" of 60 rounds at 60 CR.
- Ammo Max does not account for the current belt, so a total of 2,190 rounds (belt and reserve) when at max ammo capacity.
- Class 4 multi-cannons while seeming to have a low rate of fire (3.0/s for fixed, 3.4/s for gimballed), actually fire two rounds of ammunition at the same time giving a projectile count of 6.0/s and 6.8/s for fixed and gimballed respectively.
