Capture the Flag is the name of a game played with two teams, each with one flag. Each team's goal is to take the other team's flag and bring it back to their own flag, scoring a point and returning both flags to their original positions. However, if you bring your opponent's flag back to your flag and your flag is missing, your flag must be returned in order to score. You drop a flag when killed, and when picked up, dropped flags return immediately to their appropriate flag stand.

The CTF Standard

The modern CTF Standard is an informal agreement between various port authors that consists of a list of agreed-upon thing IDs for player starts and flags to use. It started as the result of a conversation between Alex "AlexMax" Mayfield and Brad "Carnevil" Carney, with a proposal by Carnevil to make CTF maps easier to make for Skulltag, seeing the explosion of popularity of CTF mapping in ZDaemon. From there, AlexMax convinced both Carnevil and the administration of ZDaemon to both implement what is now known as the CTF Standard. Since then it has been adopted by Odamex and Eternity will be following soon.

The standard thus far defines the following thing IDs:

  • Thing ID 5080: Blue Start
  • Thing ID 5081: Red Start
  • Thing ID 5130: Blue Flag
  • Thing ID 5131: Red Flag

When creating a CTF map, ensuring these thing IDs are in place will allow greater exposure of your map to users of all standard-supporting engines (engine-specific effects and level formats notwithstanding).
