Prevent the zerg beacon from being destroyed, kill all the zerg that continue to attack (~ 15 minutes).
It is currently mostly useful as a 'proof of concept' type map. When units gain a level they gain a 'point' which you can use to upgrade defence, attack, or life/shield leeching stats.
This is the first map i have ever made in any editor. I wanted to create a basic or concept 'castle defence' type map with xp gaining and upgradable basic troops. It is not finished, I'm not sure if/when i will get back to it, i want to gain more familiarity with editor working on other types of maps before i worry about focusing on and balancing one map.
Some things. The Ghost is a solid long range unit, outranging all zerg units. Due to upgrades using an ability, this causes the unit to lose the hold position command. As a workaround i added an ability that cuts movespeed to '0' its not actually 0 though they move very slow. But it mostly prevents your zealots from moving too much and opening up to the forces attacking. The ability is toggle-able so click it to prevent movement, and click it to let them move again.
