Rvd starts top left Vapor starts bottom right Both players use similar build orders, covering all 3 starting metals and then five goes for jeffies and flash, while vapor makes cons for 15 mins :D
Rvd takes both corners, and vapor is just outside that area with tons of MTs guarded out by his comm on the left and made by many cons on the right side. Vapor makes his geos fast and uses them to his advantage with metal makers.
At this point the metal production is about the same and rvd has way more land, rvd could have built a lot more but just threw flash at Vapor's defence without doing anything. Once Vapor has the land he wants he masses samsons and bursts through the top and kills rvd, game over.
