Addon SCP Foundation is an Android application developed by Rudio Studio Craft in the Education & Reference category's Books subcategory. This add-on introduces new mobs from the SCP universe into the game, with each mob having its own unique abilities. The add-on includes most of the SCPs found in SCP – Containment Breach, some retextured blocks, and non-anomalous items.

One of the most hostile mobs in the game is SCP-173, which won't move if the player looks at it. However, it will make the player blink, making it easier to attack. SCP-049, also known as the plague doctor, infects villagers and turns them into zombie villagers, while also attacking players and giving them a wither effect, turning them into SCPZombie).

The add-on also includes several custom items such as guns, which can be traded for ammo and used to reload guns. The P-90 and AWM have 3D models, and players can hold a firework in their offhand while using them. However, players should be cautious as all mobs can kill them.
