Ammo Chance On Kills
Repurposes spent ammo from fallen Gundead.

Ammo Synthesizer is a passive item.


  • Adds a 10% chance to regain 5% of the currently held gun's maximum ammo (rounded down) upon killing an enemy.


  • Synergy.png Extreme Operation - If the player also has Melted Rock, Melted Rock causes each corpse to fire a bullet at a nearby enemy in addition to exploding.
  • Synergy.png Synthetic Shield - If the player also has Heart Synthesizer or Armor Synthesizer, grants a familiar that orbits the player and blocks shots. If all three synthesizers are picked up, grants three familiars.
  • If 5% of a gun's maximum ammo is less than 1 (less than 20 maximum ammo), Ammo Synthesizer will restore 1 ammo when it activates.
  • Works well with Ancient Hero's Bandana as it will restore 4x more ammo effectively making it easier to not run out.
  • Works well with Makeshift Cannon if it activates.
  • If duplicates of this item are somehow obtained, increases the chance of ammo returning after killing an enemy.
