AC-8 Autocannon

"'A fully-automatic cannon effective against light vehicle armor. Includes support backpack required for reloading.'"

The AC-8 Autocannon is one of the stratagems available to the player at Level 10, costing 7,000 Requisition Slips. It is highly effective against bots and can be used as an automatic Railgun with increased versatility and less potential damage and accuracy.

Gameplay Tips

 * Unlike other weapons, the Autocannon is not fully reloaded at once, instead adding 5 shells (half) per clip. Reloading is only possible with 5 or less shells left (only a completely empty magazine will result in a double reload). It is also one of the few weapons that requires a special backpack to carry any reserve ammo and an assisted reload mechanic (allowing another player to help reload the weapon much quicker than the user).
 * Similar to some other backpacks, the amount of clips it is holding is visually represented, with yellow clips standing out from the black empty slots.
 * Naturally, the reliance on the backpack restricts the use of other backpack equipment.
 * Can be used to destroy bug holes and bot fabricator from any distance so long as the user has an appropriate line of sight with the target. Destroying bot fabricators can prove to be rather tricky as the wielder needs to ensure the projectile hits the fairing properly to ricochet into the fabricator's exhaust.
 * Capable of penetrating medium armor and can sharpshoot the weak points of heavy enemies such as Titans rather effectively.
 * Can be reloaded by the user if they have the Autocannon backpack equipped, thus allowing it to be used in solo play or without team coordination. Nonetheless having an ally reloading your Autocannon lets you shoot without any breaks until backpack ammo runs out.
 * It's advised to reload after firing around 5~9 shells instead of waiting for the magazine to be depleted. This allows the Helldiver to reload only one half of the magazine (5 Shells) which will take less time than a full reload. Reloading a fully depleted Autocannon can be canceled with a dive, while still being able to fire the shells reloaded with the first clip halfway through.
 * Firing has substantial recoil that is far more noticeable when firing in full auto. It is always recommended to fire while crouched for a dramatic decrease in weapon sway; prone being even more effective. Sporting armor that features the Fortified or Engineering Kit passive abilities helps tremendously as these both make the recoil reduction effects of crouching or going prone 30% more effective than they already are.
 * Solo reloads (even single clip) is fairly slow and requires standing still, so with the high recoil this is definitely not a good weapon when high mobility is required. Other weapons should be used for firing on the move and reloading should preferably be done behind cover and no enemies in the immediate vicinity.
 * Is highly efficient at fighting Automatons.
 * Usually takes a single shot to destroy a scout strider, neutralizing its driver as well.
 * Hitting a Devastator will stagger it and interrupt its attack, this is very important when facing Rocket Devastators and Heavy Devastators. Hitting the shield of a Heavy Devastator will also stagger it and expose its torso.
 * Can be effectively used against Tanks and Cannon towers by hitting their rear exhaust 3 times which requires rather fast shooting before enemy has time to turn.
 * Effective against Bruiser and Obliterator variants of Hulks which will stand still and face the player while unleashing their attacks, 2 shots to the glowing red visor will eliminate them however caution and staying near cover is advised.
 * Static Automaton Emplacements like Anti-Air Emplacements and Mortar Emplacements can be effectively destroyed by the Autocannon with 4 shots to the rear vent on each turret.
 * Can take down Gunships with 2 shots to one of the engines.
 * Can destroy a Factory Strider with 7 shots to their underside, this is highly risky, and Helldivers should attempt this only when the Factory Strider isn't alerted. Immediately run once destroyed to avoid being crushed.
