Author Info

Updated: September 5, 2019

Ever want to create one of those massing games (ie, family guy madness, evolves, super smash bros) you constantly see on Its easy! just follow these steps!


  1. 1
    Create locations (right click, layer, locations) for player bases (label them things like "p1 base" and "p1 spawn")
  2. 2
    Create bases for all the players (usually photon cannons, but you can make it whatever)
  3. 3
    Open the triggers menu.
  4. 4
    Delete all previous triggers.
  5. 5
    Select "Create new trigger"
  6. 6
    Select a player (player 1, player 2, etc.)
  7. 7
    Click next
  8. 8
    Select "Kill units"
  9. 9
    Specify "Current Player(using 'current player' instead of 'player 1' is easier because you can copy over the trigger and not have to rename which player it is) kills at least 0 any unit"
  10. 10
    Create another "Kill units" trigger.
  11. 11
    Specify "Current Player kills at most (this is important...there has to be one "at least" and one "at most" or the trigger will not work correctly) [specify desired amount of kills before upgrade] any unit"
  12. 12
    Click next.
  13. 13
    Create trigger "create units"
  14. 14
    Specify "Current player creates 1 [whatever you want the level 1 unit to be (ie protoss zealot)] at location [whatever location you want the unit to spawn (such as the aforementioned 'p1 spawn')]
  15. 15
    Create trigger "preserve trigger" (this is vital, it makes the trigger repeat over and over as long as the conditions are met (so if you were to have put in "kills at most 100 any unit" then the player would keep spawning its level 1 unit until they had more than 100 kills)
  16. 16
    Repeat these steps for however many levels you have (continuing the "kills at most 100 of any unit" example, your next trigger would be "current player kills at least 100 of any unit" and "current player kills at most [whatever it is to the next upgrade]")
  17. 17
    Create a leader board [All Players > Always > Leader Board (Kills)]
  18. 18
    Save the map and you're ready to go!

  • Download a "special" editor off the internet, the default one is really limited. (Ex. Google "Xtra Editor")

  • Make sure you change the unit when you change the "kill" requirements (Ex. "kill at least 100" "kill at most 200", then it would be "create Protoss Dragoon" instead of zealot)

  • This isn't that hard to do, however, it is quite time-consuming.

  • There is no guarantee that your map will gain popularity on (actually, there is a good chance it won't...there are simply too many massing maps out there already)
