MTF Epsilon-11, nicknamed Nine-Tailed Fox, is the Mobile Task Force squad sent to handle the containment breach of the SCP: Containment Breach Nine Tailed Fox Mod.
As in the original SCP - Containment Breach, they are a nine-man team evenly split into three groups. The player is in one of these groups, and thus has two friendly NPCs at their shoulders.
The NPCs' AI mindlessly patrols the facility. They are currently invincible (but will eventually be killable) and have unlimited ammo for their P90s, so they are very helpful allies during Class-D encounters. They're also very helpful in SCP-173 encounters, as they effectively disable it as a threat by having so many eyes trained on it, making its recontainment easy. It's very easy to get separated from them, however, and due to the maze-like, randomly generated map, are hard to find after separation. They instantly spawn at the player's side whenever they go through a checkpoint, fortunately.
- The two operatives are voiced by ItsDuke and Alex Morganidze, and thus have American and Russian accents.
