This map is similar to temple siege, but better.

You start out by picking your hero. Hot key your hero as #1, then @ bottom right corner of map (or top right, I think), hotkey stargate as #2 for your main spells. Robotic facility is miscellaneous stuff.. Hotkey your upgrade building @ upper area of the map as #3. Hotkey your comsat station nearby your stargate as #4.

Heal @ academy. Kill for level up & $$$. Experience points are indicated by bar @ bottom & top areas of map. Mineral is for upgrades, but the total score, dubbed as "gold" is displayed at the leadership board at top left corner of your screen. With gold, you can "buy" items with your dark archon at middle left area of the map, whenever your hero goes to academy & heals.

Different combinations of spells bring different results... i.e. 2 scouts are different from 1 scout spell, and you can combine corsair (ultimate) with other spells as well.

Some help with gameplay:
The Stats System is on the upperright part of the map (SCVs)

The Bottomleft Dark Archon is the shop, usable only in the pylon radius of the base.
