Playthrough: https://www.youtube.com/playlist?list=PLACFHAM2MlxNqgmviFjKo2Qp_TYNAirfM

The Confederation continues its onslaught against the Zerg, and the Protoss continue confusing the player.

11 playable missions, 2 cutscenes, 1 cinematic, two modded executables for version 1.16.1, nearly-fully voice-acted
Not recommended on the grounds of intolerable level design, a complete lack of organic macro gameplay, and buggy triggers.
