In Game[edit]

At the start of the round, Class-Ds will spawn in the Class-D Cells without any items, and must search Light Containment Zone for items that can assist in their escape, while watching out for any other threats like SCPs.
Given no items, Class-Ds are generally considered the most difficult class to play, especially since they are hostile to almost all other classes.

A Class-D's goal is to get to the Surface and reach the escape room (near the MTF spawn) and escape, respawning them as a Chaos Conscript. This will also give the Chaos one Respawn Ticket, allowing one more Chaos to spawn during that round.
If the cuffed_escapee_change_team config option is set to true on a server, a Class-D that escapes while disarmed will become a Mobile Task Force Private. This also gives the MTF one Respawn Ticket, giving them 2 more teammates in that round per disarmed Class-D that escapes.

Strengths and Weaknesses[edit]


  • One of the 2 classes who are notified if Chaos spawn in (via the Chaos theme).
  • More Class-Ds spawn than any other class at the start of the round.
  • With proper coordination, D-Class have the ability to become one of the greatest threats to the facility.


  • Don't spawn with any items or weapons.
  • Tend to be shot on sight by most players (KoS).
  • Are hostile to all but one class in game.
