Building (Name): Function
Command Center (Torpedo Launcher): Lift to create 2 Scourges at your position. Build ComSat to create 3 Scourges. Build Nuke Silo to create 4 Scourges. Dies after one use.
Supply Depot (Small Armor): As long as you have at least one of these, all your other buildings are invulnerable.
Refinery (Engine): Required for movement.
Barracks (Special Weapon Launcher): Lets you use your ship's "signature ability": Yamato Gun, Cloaking, or Defensive Matrix/EMP Shockwave if you are playing as a Battlcruiser, Wraith, or Science Vessel; or HALO Rocket Swarm (creates ONE clone of your ship every time you get a kill) for the Valkyrie.
Engineering Bay (Nano-Repair System): Lets you upgrade your armor. (Whenever you research Terran Infantry Weapons, your Observer's HP goes up.)
Missile Turret (Point Defense System): Create and remove one invincible marine (turret) that attacks once underneath you every 6 seconds for each turret you have in your base
Bunker (Cockpit): If your SCV is not in the Cockpit, you can't control your ship.
Academy (FTL Drive): For each of these you have, you have a shuttle with 8 Broodlings in each. If you drop one, an animation is played, the Shuttle dies, and you are teleported where you dropped the broodling. Then after 4 minutes of "recharging", that shuttle is recreated.
Factory (Signature Weapon): Create a Vulture (costs gas only) to activate your special skill. For Battlecruiser, the skill creates a Meteor Swarm around you: Seven "Meteors" (Kakarus) come falling down to random positions (determined by JYD units) near your ship. The Wraith's skill spams Dark Templar underneath it which last for about 8 seconds. The Science Vessel's skill launches a missile towards the top of the screen. The Valkyrie can plant a Time Bomb (Psi-Emitter) under it which explodes in about five seconds. You get XP from kills from your skill. Against bosses, the skill's effects are a lot weaker (or maybe totally nonfunctional). You gain gas at a rate of 1 gas unit per Factory per second, to a cap of 200 gas. If you build a Machine Shop, you can build Tanks, which also activate your special but cost less. (Machine Shops are very expensive, though...)
Starport (Reactor): Same as supply depot, but with more life.
Armory (Weapons Array): Required for firing/Irradiate.
Science Facility (Tactical AI): You gain extra XP per kill! Create Physics Lab or Covert Ops for even MOAR bonus XP!

Building (Name): Function
Nexus (Psionic Bomb): Create a probe to make an explosion beneath you that destroys all ground units underneath you. One time use.
Pylon (Power Node): Necessary to build stuff. Low life and low cost.
Assimilator (Gravitric Drive): Required for movement.
Gateway (Enhanced Psionic Link): Build unit to enable signature feat. The Carrier's feat is to instantly jump up to 8 Intercepters for a few seconds. The Scout's feat is temporary invulnerability. The Corsair's feat is Distruption Web. You can create any of the gateway units, with Zealots being the cheapest and Dark Templar being the most expensive. The more expensive units are better, because they make the duration of the feat longer (for the Scout, and Carrier), or have a shorter cooldown (for the Corsair). With the arbiter, built units stick around in your base and can be recalled to the battlefield.
Forge (Plasma Shield Matrix): Research Protoss Ground Weapons to increase your vHP's HP.
Photon Cannon (Anti-matter Cannon): Create and remove one invincible archon that attacks once underneath you every 6 seconds for each, so you need to be right on top for it to work..
Shield Battery (Reserve Shield Plasma): Every few seconds, your vHP's shields are restored to full. It takes less time for each battery you have.
Cybernetics Core (Tactical Locus): Required for attacking. For the Carrier, for each Core you have, you can have one more interceptor. If you ever have more interceptors than cores, one interceptor is killed. (feel free to dispute this)
Stargate (Warp Gate): Functions just like the Terran Academy.
Citadel of Adun (Shield Matrix): Functions just like the Supply Depot.
Fleet Beacon (Khala Link): If destroyed, complete loss of function - Must be placed in correct spot
Templar Archives (Armor Matrix): Functions just like the Citadel of Adun, but with more HP.
Robotics Facility (Psionic Weapon): Enable special skill. The Scout's skill creates explosions (Kakaru deaths?) all around it for a few seconds. For the Carrier, like 25 invisible wraiths are created for him at his location for visual effect. They all travel towards the Carrier. While this is happening, a medium-sized location is centered on the carrier and every second for 5 seconds, every non-boss in the location dies in a blue explosion. After the 5 seconds are over, all the wraiths die. The Arbiter Special is - A nuke like missile (observer) comes down from the very top of the screen killing every non-boss unit in its path and when it reaches the arbiter, a large explosion is created. It will take a little while for the missile to reach you from the top of the screen, but it is worth it! The Corsair's special is that a recall swirly black hole thing is created on your Corsair, all units on screen walk towards it, and once they get there, they (except bosses) are removed and you get the kill. This special lasts for 6 seconds, so some units need to be closer to you in order to reach the black hole.
Robotic Support Bay (Improved Psionic Weapon): Lets you create Reavers at your Robotics Facility, which also activate your skill, but cost less.
Observatory (???): No function currently.
Arbiter Tribunal (???): No function currently.

Building (Name): Function
Hatchery (Overmind Link): Necessary for control of your zerg unit; if this dies your zerg unit is given to player 12 and is ordered to junk yard roam until you build another one. Also, this is where you build many units for the overlord and drones for all zerg.
Lair (Improved Overmind Link): Serves the same purpose as the hatchery, except it has more life.
Hive (Ultra Overmind Link): As above, but with even MOAR HP.
Spawning Pool (Thicken Skin): See Supply Depot.
Creep Colony (Circulatory Chamber): Normal function. Only useful for morphing into Sunkens/Spores.
Extractor (Air Bladder): Required for movement.
Sunken Colony (Adrenal Glands): Whenever you kill an enemy, you get a bunch of Mutalisks at your position for a few seconds.
Spore Colony (Improved Thickened Skin): For each of these you have a lurker is created beneath you every 6 seconds and fires once.
Evolution Chamber (Chiten Enzyme Gland): Research Zerg Melee Weapons to increase your vHP's HP.
Hydra Den (Toxic Spines): As Spawning Pool, but more armor.
Spire (Acid Glands): Required for firing.
Queen's Nest (Egg Sac): Kill this (as long as it is finished) with your drone (or it might be killed by an enemy) and 10 broodlings pop out to fight for you.
Greater Spire (Special Acid Glands): Enable signature feat. Mutalisk feat is to morph into a Devourer or Guardian (takes 7 seconds to take place) and then you create zerglings from your hatchery to morph back (takes 7 seconds), Queen feat is to become a hero Queen, thus enabling ensnare which costs 3 energy and expanding energy capabilities to 250. Overlord Feat is to evolve into a hero, thus increasing sight. Note that having more than one greater spire is redundant.
Ultra Den (Warp Morph): See Academy.
Defiler Mound (Resistant Chiten): Enable signature skill (Create Defiler from hatchery to use). The Mutalisk Skill is to create 1 weaker enemy-type mutalisk, 1 weaker enemy-type guardian, and 2 scourge to fight for you until they die. The Queen Skill is to create an Infested Terran that rushes toward an enemy unit and, when exploding, instead of killing the units it splashes, it converts them to your side. The Overlord skill is to create a dark archon inside next to the Greater Spire that you created that has all of its skills (mind control costs 150 to cast, feedback 50, maelstrom 100) to drop down to the field below. It fights for you until it dies, so you can build up many of these!
Nydus Canal (Tendril): Place the Nydus Canal "copy" any place on the map (doesn't matter where) and it will place an ultralisk directly underneath you.

1. I liked the old function of the missile turret where every few seconds a marine is created underneath you to fire (more often with more turrets). I suggest making the Starport the large armor instead and simply dropping the Starport's current function.
2. 20 seconds is a long time for DT's to be spammed underneath the wraith. Maybe about 8 instead?
3. I think that making guys run from the time bomb would really reduce its effectiveness. Right? Otherwise I like it.
4. Buildings are quite a bit tougher than other units. Should skills kill buildings as well? I suggest it reduce (or increase, unfortunately) the buildings' hit points to 35%?
5. For the pylons, I really like making it so you have to build pylons, it makes the protoss different than other races. And it's not so bad if the pylon gets hit, just make another one (they can be cheap, not time expensive but weak). I think it would be cool. But probably buildings should still function if the pylon is gone, just not the ones you have to trigger like the starport. Agree?
6. I think the Arbiter's feat (from gateway) is kind of lame. Do you not like the idea that the units created stay in the arbiter's base and he can recall them out?
7. Why don't you like the idea of making it so that the carrier has as many interceptors as cyber cores? I think that it would be cool because it emphasizes that you are kind of building a ship. And then whenever you have more interceptors than cores, it displays an error message and kills an interceptor (interceptors would be like 1 mineral to build but archives would be like 50).
8. The carrier's feat won't be that great if the player already has 8 templar archives (that is, if we like the above idea), so another idea would be to convert all interceptors into scouts for 5-20 seconds, depending on the unit you chose. Like?
9. I recommend the greater spire being upgraded be changed to enable feat:
and then the ICC being changed.
10 How is the ICC created? I really think that it would be better to scrap the icc and use it as a boss. Instead I recommend changing the Defiler Mound to the skill enabler, and simply creating a defiler at the hatchery triggers the skill.
11. The nydus canal function is kind of bad because it ONLY works at the very end of the map, when you are fighting the zerg. I recommend making it so that whenever you have two nydus canals anywhere, they are both destroyed and a strongish ultralisk is created underneath you.
12. It would be nice if the corsair had some kind of ground attack. I recommend changing the photon cannon's function to "for each photon cannon you have, an archon is spawned every 5 seconds that has time to attack once and then disappears."
13. I like the shield battery's function more if, every few seconds (we'll say 6 until we test it further, less if you have more shield batteries), the observer's shields are restored to full. Do you like that better>?
14. I recommend switching the Hydra Den and Spore Colony functions so that the spore colony and sunken colony have similar functions.
