Waaaay back in first year, my floor mates and I had a grand old time using the university's network for Starcraft. I was always the Terran player, everyone else was either Zerg or Protoss. Anyway, after a long grueling match, there are only two of us left, myself and another guy playing as Zerg. Now, both of us have more or less milked the map for credits, he's gone with the Zerg swarm and I've got bunkers with Marines.
So he sends in his horde, Zerglings then Hydras, they aren't doing so well so he sends in some Mutalisks and Scourges to take down my Wraiths and Battlecruisers (yes I was a Battlecruiser whore). Still, my defense is rock solid. Sends in the A-Team next, Ultralisks and Guardians who manage to take out a couple of bunkers and punch through only to be stopped cold by my second line of bunkers.
Now he's got this huge swarm of Zerg milling around my first bunker line and I, being the asshole that I am, nuke the entire line after having pulled out the majority of my Marines. After that, there was no more cash and so I just kind of steamrollered him with my Battlecruisers.
