Ammo is a type of resource found in SCP: Secret Laboratory, which is used as ammunition for the various guns in the game.

Types of Ammo

Currently, there are three different types of ammunition present in the game, along with different models to distinguish between each. They include:

Ammo Type Used By Description
5.56mm Epsilon-11 SR This appears as an AR-style magazine, being rectangular and grey.
7.62mm MP7, Logicer This appears as a curved AK-47 magazine.
9mm COM15 Pistol, Project 90, USP This appears as a small, black pistol magazine.

Each class is granted a standard quantity of ammo at the beginning of the round and when they respawn for the three types of ammunition at varying quantities, depending on the class. As such, the base quantities of ammo for each player is:

When a player is killed or detained by the Disarmer, they will drop their ammunition alongside their weapons/items. This allows for efficient kills to net the attacker ammo to continue fighting.

A player can obtain ammo if another player gives up some of their own by using a Weapon Manager Tablet to drop packets of any ammo type they choose as long as they have enough to make a full packet.


The Armory in the Light Containment Zone can provide a few 9mm and 7.62mm pickups.


Weapon Locker Type 21 can provide multiple pickups of all ammo types. The MTF-E11-SR Rack only provides 5 5.56mm ammo pickups.


  • Many of the weapons in the game use different calibers than they do in real life, e.g. the Logicer (Based on the Stoner LMG styles) actually uses 5.56x45 NATO.
