Discover all ammo types in The Callisto Protocol. Learn about their uses, effectiveness, and how to find them to maximize your combat efficiency against the horrors of Callisto.

The Callisto Protocol features several distinct ammo types, each with its own strengths and weaknesses. Understanding these is crucial for survival against the game's relentless Biophage enemies. This guide will break down each ammo type, detailing its effectiveness and how to acquire it.

  • Standard Bullets: The most common ammo type, suitable for general-purpose combat. Effective against weaker enemies but may require multiple shots for tougher foes. Found frequently in the environment and on defeated enemies.
  • Shotgun Shells: Deals high damage at close range, excellent for staggering enemies or taking down groups. Less effective at longer distances. Primarily found in weapon caches and sometimes dropped by specific enemy types.
  • Handgun Ammo: Typically used with pistols, this is a reliable ammo type for precise shots. Good for conserving other ammo types or for targeting weak points. Scavenged from fallen enemies and found in small quantities throughout the levels.
  • Special Rounds: These are rarer ammo types, often tied to specific weapons or found in limited quantities. They can have unique effects like increased damage, armor penetration, or elemental properties, making them invaluable for boss encounters or particularly challenging enemy waves. These are often found in hidden areas or awarded for completing specific objectives.

Managing your ammo is key to survival. Always be on the lookout for ammo pickups and consider which weapon is best suited for the current enemy threat to conserve resources.
