Just a Scratch
Points

Criteria
Repair 1,000 life on allied structures in a single Melee game.
Notes
This achievement is obtainable in custom games with AI players. Repairs must be done on allied structures, not your own. Damage on allied structures must be enemy inflicted.
Destroy 10 cloaked or burrowed units in a single Melee game.
Notes
Cloaked units killed inside transports are count. In a League game, there's the possibility to combine this achievement with Raining Blood, if the transport is full of dark templars.

Zerglot
Points
10
Criteria
While playing as Zerg, warp in a Zealot in a Melee game.
Notes
The easiest way to do this is play as zerg vs a friend playing as protoss. Also possible is playing zerg with a protoss ally; the ally leaves the game and one can use his gateway to make a zealot.(Alternatively, play against a easy or very easy protoss AI. Destroy all of the opponent's buildings except one, without hurting the probes.) Use an infestor to infest a probe, and use it to build a nexus (and a pylon if there's time enough). From this nexus, build a probe, and warp in a pylon, then a gateway. Then you can create a zealot.
Distorted Reality
Points
10
Criteria
Capture 50 enemy units in a single Vortex in a Melee game.
Destroy 20 units with Sniper Rounds in a single League game.
Notes
This achievement is a reference to Team Fortress 2's Meet the Sniper video, where the Sniper says "Professionals have standards: be polite, be efficient, and have a plan to kill everyone you meet." In Team Fortress 2, there are achievements titled "Be Polite" "Be Efficient" "Have a Plan" and "Kill Everyone You Meet" but no achievement titled "Professionals Have Standards".

Criteria
Warp in 100 units with Warp Gates in a single League game.
Unbreakable!
Points
10
Criteria
Destroy 40 units with a single unit in a single League game.
Notes
Kills made by nukes are count, so this achievement can be earned by droping 2-3 nukes launched by the same ghost.
This achievement is a reference to Team Fortress 2's Meet the Spy video as an introduction to the class 'Spy', who could disguise as enemy players, but also instant kill via backstab and disable buildings (which aren't things the Changeling is capable of).
