Class-D Personnel are a civilian class that spawn in Light Containment Zone. Their goal is to get to the Surface and escape.

In Game[edit]

At the start of the round, Class-Ds will spawn in the Class-D Cells without any items. Their goal is to get to the Surface, and escape, which will respawn them as a Chaos Conscript. This will also give the Chaos one Respawn Ticket, allowing for one more Chaos to spawn during that round.
A Class-D that escapes while disarmed will respawn as 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 (This can be disabled by changing the server setting cuffed_escapee_change_team to false).

Class-Ds win alongside Chaos Insurgents with a "Insurgency Victory" if the amount of D-Class escapes is higher than the amount of Scientist escapes, and all other classes are dead.

Strengths and Weaknesses[edit]


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


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

  • According to former Game Designer, Wavepoole, Site-02 doesn't hire actual janitorial staff, and uses Class-D instead.

  • There were going to be 4 other Class-D models that players could select from the Customization menu at one point. 3 of those models were female and 1 was male.
    • These variants would even have gotten their own stats, advantages and disadvantages.
      • These models were left unused, as the customization system was scrapped.
