Everything I did in that map was for the most part original. I didn't invent anything in that, but I did modify some already invented systems.
The place to upgrade is in a corner, and lets you make pretty much any units you want which would be useful, rather than having a civilian based system like most other defenses have.
The kill counter is based off of Legacy Weapon's perfect kills to cash, but I changed the triggers so they work significantly faster, and so that the units (zealots) die much faster by using constantly attacking flame traps. It limits the number of attacks, unfortunately. I may change it to zerglings later, but I really don't care about the map anymore.
The increased max supply is from Farty, and I just threw that in there as an example. Plus, it only uses 1 unit to give max supply.
The banning system was entirely developed by me, and fails miserably, since people are idiots, and I didn't give a description of how to use. Pretty much, you build a number of scarabs, and then move the reaver to the beacon to ban that player #.
I've never seen the moving larvae to another area in another map, but IMO, it's pretty simple. It just took some time to get the larvae to stand still.
I do like how you can't actually fly out of the playing area, though. That seems to work well, and uses cloaked buildings to do it.
Now that I think about it, it's more of a compilation of a bunch of concepts, rolled into one terrible defense.
