A mod for ULTRAKILL that adds an ammo system. Whenever you fire any of your guns, you lose ammo. You cannot fire a gun unless you have ammo for it. You can regain ammo by:

• Killing enemies. You get more ammo depending on the enemy type and your current style rank.
• Parrying. Parries will restore your ammo to full. Additionally, in the Cyber Grind after completing a wave your ammo will be replenished to at least half of the maximum value.
