Effective Mid to Long Range Weapon

Effective Mid to Long Range Weapon

The Heavy Cannon is a great weapon to use when engaging enemies from mid to long range. It features a fully automatic firing mode, allowing you to spray and focus on enemies without having to get too close to them.

Consumes Bullets

The Heavy Cannon uses bullets as ammunition. It shares the same ammo type with the Chaingun, so managing how much bullets you have is necessary as the Chaingun can eat up your supply quickly!

Efficiently Kill Fodder Enemies

Efficiently Kill Fodder Enemies

The Heavy Cannon is an excellent weapon to use when facing fodder enemies such as Zombies and Imps. A single shot to the head or 2 body shots will more often than not be enough to kill them. A highly efficient weapon when not facing notable enemies!

Useful For Destroying Weak Spots

Useful For Destroying Weak Spots

The Heavy Cannon is also one of, if not the best weapon to pick off enemy weak spots! You can use this to destroy heavy enemy weak spots at range before closing in for the kill!

Not Recommended to Finish Heavies

Despite it being a great way to start fights against heavy enemies, it would be best to switch out to another weapon when trying to finish them off to further conserve your bullets!

Precision Bolt - Heavy Cannon Mod

Turn Your Cannon Into a Sniper Rifle

Turn Your Heavy Cannon Into a Sniper Rifle

The Precision Bolt will allow you to aim down the scope of the weapon, and target enemies at a much longer range. It will also slow down the fire rate of the weapon, and increase ammo consumption to 6 rounds per shot, but will deal much more damage. Effective against weak spots.

Available Upgrades Precision Bolt Mod

It is recommended that you invest your Weapon Points into the Fast Loader upgrade first as this will allow you to pick off multiple weak spots much faster!

Unload Rockets Onto Enemies

It is recommended to focus on getting the Primary Charger upgrade first as this will temporarily boost your missile damage, allowing you to become more of a threat when using the mod!
