"We're back to the practical exercises this week, kids." If Kerrigan was going to comment on being five minutes late... well, she wasn't going to comment. "We talked about resource gathering a while back. Now, of course, you all understand the importance of keeping your resources up. If you flip that around, that means one of your prime objectives should be taking out your opponent's ability to gather resources."
She shifted her weight to one hip, then pressed a button. The Danger Shop environment gave way to the Badlands again, with two small bases on either side-- one command center, some resources, and a couple of SCVs. "In this simulation, your objective is twofold. First, you have to gather as many minerals as you can. Second, you have to try to disrupt your opponent's ability to gather resources. There's a couple of ways to do it.
"For example, you can block your opponent's access to the minerals by building a bunker in the right location. Of course, if you want to manage this, you have to strike quick, early, and well, because otherwise your opponent's SCVs can simply dismantle the bunker before it's finished. You can also simply assault the SCVs with your own, and hope your tactical maneuvering's decent enough to beat your opponent. Anything else... well, I leave up to your ingenuity."
She rubbed her forehead with two fingers. "Any questions before we begin?"
[ wait for the ocd up! remember, kids, scvs can gather resources, build structures, AND fight. sorta. only in close-combat ]
