Why do new facilities have Vespene and minerals breaking through the floor?

i was recently deployed to fight the zerg on our newest orbital platform.

Midway through the fight i found that they were harvesting both vespene and minerals to fund their war efforts... in the middle of our brand new platform!

I have seen similar things on other campaigns, minerals breaking through the top of sky scrapers, inside our most secure facilities.... what gives? Why are we paying the zerg to fight us?

Most of those structures are actually infrastructure built around existing mineral and vespene deposits. It's a pain to fly an SCV halfway across orbit just to deliver a single load of minerals, so decades ago Terran terraforming ships went all across the sector building roads and platforms so that colony ships would have easy access to resources later. A lot of those structures were actually built decades ago, back before we made first contact with the Zerg, and the colonies that were supposed to be built near those deposits were either delayed due to a lack of volunteers, high murder rates depleting the indentured convict population, political infighting delaying the consturction of colony ships, and (most recently) colony programs being cancelled in favor of military development to fight the Zerg, Protoss, and Dominion.

The bad news is that it's your parents' taxpayer dollars being wasted due to poor planning. The good news is that if a military engagement takes place anywhere in this sector, you won't have to look far to find a great place to drop a command center and start field-production of materiel.

The few mineral piles and vespene geysers you've seen indoors *(like in the tutorial mission of Heart of the Swarm)* are usually simulated test environments for testing new extractor tech for SCVs and MULEs.
