"An old boarding axe, forged and abandoned by the followers of Cannonbalrog. Though the blade is pristine, it has a strong sulfuric odor."

This mod adds a new custom gun called the Privateer's Cleaver, a (mostly) melee weapon that allows you to combo enemies! Fire a projectile on your initial swing to target an enemy, then dash towards them and swing until they're dead. For a little extra flair, there's also some custom particle effects and even a few 3D indicators.

It gives you 2 curse while you hold it, and has 5 different synergies.
Cannons Away (w/ Serious Cannon) - Doubles the amount of projectiles that explode from an enemy on death, and greatly increases the damage of these projectiles.
Combo King (w/ Katana Bullets, Knife Shield, Boxing Glove, Excaliber, Fightsabre, Huntsman, or Wood Beam) - Doubles the amount of damage that a melee swing does to an enemy.
Destination Locked (w/ Corsair) - Makes the player's dash towards the enemy near instant.
Hyperspeed Swing (w/ Gunboots, Bionic Leg, Shotga Cola, Shotgun Coffee, or Ballistic Boots) - Makes the gun's animations 50% faster, resulting in fast melee swings.
Axes Don't Reload (w/ Cog of Battle) - Removes the forced reload after melee killing an enemy, allowing you to instantly shoot another projectile and combo a different enemy.

This mod was created for the first GunJam with the theme Pirates. You should be able to install it like any other mod.
The id for the weapon is spc:privateer_cleaver. So, use give spc:privateer_cleaver to give yourself the item.
