Just me wanking (not soviet wanking, just turtling really) around in ranked 1v1 on seraphim site. I was planning the usual AC 1000 rush, however then I had to get cluster bombs and structure guns for defence, so I decided that I'd get a few other things that I don't get to use in ranked.

Ignore the ACU upgrades, just got them for fun as I had tons of research.
