UA LIST

(1) Sejong's Starleague
-Gain 1 gas per each variety of non-defense buildings you've built, but start with three workers. Add-ons count, and buildings do not need to survive to retain the bonus.
*This of course is referencing Civ V's Sejong godstomping with science, as well as Koreans godstomping Starcraft with micro.

(2) Blood and Iron
-Gain triple minerals from razing.

(3) Strength Through Labour
-Start with 2 more workers than normal, and workers periodically heal.
*A bit of a direct counter to Imperialism.

(4) Treasures of Aiur
-Gain gas per each enemy building you destroy.
*A callback to Treasures of Nineveh of Assyria.

(5) Capitalism
-Building a gas-gathering building in your capital returns a permanent investment, each of which grants 10 minerals and 5 gas every 30 seconds, and receive 50 minerals 25 gas immediately. The maximum number of investments that can be made is 30.
*Your science generation will be terrible at the start, so I'd recommend taking a gas multi ASAP.
*Idea credit: Noksek.

(6) Eulogy in Blood
-Gain 2^6-x gas and minerals periodically, where x is the number of players alive. You do not receive any aid when all players are alive.

(7) Ingenuity
-In exchange for having to build three preparations for a gas gathering building, another gas gathering building in your empire will yield as much as the capital's. Unlike the capital's, this provides the same bonus to invaders.
*A reference to Babylon from Civ V.

(8) Imperialism
-Upon researching Spire, Starport, or Stargate, the appropriate capital ship (at 50% HP and shield) will spawn in the capital if none of it exists. Zergs receive a Guardian or a Devourer, and Carriers start with 4 Interceptors.
*Used correctly it will break the game. If the opponent is prepared, it'll be near useless.
*Excellent synergy with Guardian/Battlecruiser/Carrier UUs.
*Idea credit: Noksek

(9) Espionage
-Gain the location of all buildings on the map periodically. Must research Advanced Buildings.

(10) Pleasures of Biophobia
-Become hostile towards nature. Gain 15x mineral and gas per each critter killed, where x is the number of critters killed. Also gain 400y minerals when a species is exctinct, where y is the creatures originally in existence. You monster.
-Has a side effect of becoming hostile towards minerals and gas.

(11) Martyr's Legacy
-Upon losing a unit, salvage a fifth of the mineral and two fifths of the gas cost of the unit.

(12) Wayfinding
-Start with a dropship or shuttle if Terran or Protoss. If Zerg, start with the Ventral Sacs upgrade.
*A callback to Polynesia from Civ V (why is Polynesia a civ again?)
*You can really abuse this by loading and unloading units before the enemy has AA.

(13) Ubermensch
-Heal all units when upon razing 750 points worth of buildings, but gain less minerals per razing. For an estimate: Hatcheries are 900, and Photon Cannons are 300. Excess points carry over.

(14) Inherit the People
-When a player is defeated, gain the player's UA, and receive 800 minerals and 500 gas.
*Pray you don't get Strength Through Labour in the midgame.
*Pray you do get Sejong's Starleague/Ingenuity in the early game.
*1.18 had broken this, and it was truly annoying to fix. Thanks Blizzard.

(15) Not One Step Backwards
-Pay 4/5 of normal maintenance fees.

(16) Prototype Overdrive
-Upon unlocking and constructing a new building, receive three (six for Zerg) units granted by it immediately. The effect only works once.
-Lurkers, archons, and dark archons won't spawn, partly because they crush everything. Guardians and devourers will spawn.
*Complements UUs excellently.
