=== Heavy autocannons ===
[[File:Heavy_autocannon.png|right|200px]]
Heavy autocannons are single-barreled and offer high damage with a low fire rate, reduced ammo capacity, and high recoil.

* Cost: $100 (heavy autocannon), $1/round (kinetic), $2/round (HE, frag, AP, and incendiary)
* Mass: 50 units (500 kg)
* Burst fire rate: 112.5 rounds/minute (32 ticks per round if infinite ammo is on, 38 ticks if it is off due to the 6 tick reloading time)
* Maximum burst fire duration: 30 seconds
* Cooldown time: 6.266 seconds
* Maximum sustained fire rate: 99 rounds/minute
* Ammo drum capacity: 100 rounds (large), 40 rounds (medium), 20 rounds (small) [1/5 the ammo capacity of drums storing light autocannon ammo]
* Muzzle velocity: 900 m/s
* Projectile lifetime (ticks): 600
* Maximum range: Approx. 2.5 km

Ammo effects:
* Kinetic: Damages blocks up to 1.25 meters (5 block lengths) from the impact point. No penetration.
* High explosive: Damages blocks up to 1.5 meters (6 block lengths) from the impact point. No penetration.
* Fragmentation: Spews shrapnel from the point of impact in all directions. Can penetrate an airgapped wall to spew shrapnel on the other side. Will also damage blocks within 1/2 meter (2 block lengths) from the point of impact.
* Armor piercing: Can pierce through three (airgapped) walls to hit a fourth. Wall thickness does not appear to matter. The first and second wall also suffers damage to blocks within a meter (4 block lengths) from the impact point, the third wall suffers damage out to 1/2 a meter (2 block lengths) from the impact point, and the last wall suffers damage only to the directly impacted point. Can only pierce through one (airgapped) wall made of armor (weight blocks) to hit a second. The first and second wall both suffer damage to blocks within 1/2 meter (2 block lengths) from the impact point. 
* Incendiary: ~25% chance <noinclude></noinclude> per shot of starting a fire at the impact point. No penetration. Damages blocks within 0.75 m (3 blocks) of the impact point.
