Hi, I was the main play tester for this mission (and the composer for the music tracks on Terminus difficulty) and this mission can be beaten in under 8 minutes.
So, fun fact about the Ai. It actually tries to avoid your army to slow you down. The whole point of the mission is the Umojan trying to stall for time so I programmed them to do just that!
Something to note is that Red and Purple don’t share vision, and that the Whirlwind doesn’t target your mineral line. I hate it in campaigns when my mineral line is harassed because all it does is make you save scum, build a few turret, and ignore it. So in the campaign the Ai will never purposely harass your mineral line. Also you can “technically” kill Cruith in this mission if you bait him over with an air unit. Killing him results in the final cutscene just, staring at nothing in pure silence.
Yea I notice that about the vision after sending max army 5times to purple and getting wiped out by the Whirlwind lol I didn't know about the harassing mineral line thing but that is nice to know since I hate getting my mineral line harassed too. I mean this is campaign, not PvP. Want to enjoy the game without getting all my workers killed:)
It took 3 hours of programming to make the AI actively avoid targeting the player’s mineral line. There was a fun bug early game n where the AI would nuke its own mineral line and I still don’t know what caused it.
