Ammo Case GUIDE

Understand Ammo Case

Useful when…

  • Increase ammo capacity for the equipped weapons.
  • Convert ammo pickups into ammunition for equipped weapons.

Effect and timing

At rank 0, Ammo Case grants +5% Ammo Capacity and converts pickups after 5 seconds. At rank 3, it grants +15% and the delay is 3 seconds; at rank 5, +25% and 2 seconds. It is a Carrier mod.

Rank and fit

This is a standard Carrier mod with Penjaga polarity, base drain 2, and maximum rank 5. The first rank costs 10 Endo and 483 Credits; the rank 4-to-5 step costs 160 Endo and 7,728 Credits. Higher ranks both increase capacity and shorten the conversion delay.

Distinguish pickup support

Looter instead emits a pulse wave to break open loot crates within 22 m. That crate-breaking effect is distinct from Ammo Case’s ammo-capacity and pickup-conversion effects.

Limitations and tradeoffs

  • Requires Carrier and a standard mod slot.
  • The conversion is delayed, with the delay depending on rank.

Common mistakes to avoid

  • Expecting pickup conversion to happen instantly.
  • Confusing the ammo conversion effect with Looter’s crate-breaking pulse.
