Design Your Own Mission (DYOM) is a multi-award-winning mission mod for GTA San Andreas made by Dutchy3010 and PatrickW. It allows to create a new mission ingame, without writing a single line of SCM script. The sixth version of DYOM brings a storyline feature to make a few missions connected to each other with a common plot. The mod works as a mission pack. The latest version is 8.0, released on 22 January, 2014.


Installation is very simple. Just copy the MPACK folder from the archive to your "San Andreas User Files" (in My Documents). To add downloaded missions, just copy the DYOMx.dat files into "San Andreas User Files". CLEO 3 is needed for this modification to work correctly.


  • Create your own missions without writing a single line of code!
  • Create objectives, pickups, cars, text and more for your missions with the use of a simple menu.
  • Share your missions on DYOM site, and allow other to play your missions, or try the missions made by others.
  • Uses Mission Packs, which were unused by R*, but left for modding.
  • Load up to 8 DYOM missions at a time in your MPACK folder.
