I was playing Lambda Wars (Think Starcraft, except Half-Life 2) with my friends. It was a free-for-all on a team-based map. One of my friends spawned behind me without me realizing, and ended up destroying my first base right after I had started up a new one, further away.
Then I return with saboteurs and destroy his everything with C4. He promptly ragequits.
Afterwards, I send more saboteurs to my other friend's heavily fortified combine base. He forgot to make scanners, so my guys just went in completely invisible and wrecked his shit, too. But he had like 3 other bases set up.
I end up having to take each of his capture points as if he's been fortifying japanese islands. Eventually, I'm at his last base, and when I scan it, I see that he has a single combine suppression device, which is usually more than enough to take out a squad of units. But since the Combine are like the Protoss, he had to power all of his buildings. He only had one powersource supplying both his headcrab cannisters and his suppression device, so I send D0G on a suicide mission, destroy his power source, and before he could realize what I've done, he says, "What was that? You only destroyed one building!"
Then I send in about 80 other units and finish him off. It was a good day. (For me)
