I destroyed it. It's not so much out of spite for The (Illusive) Man as it is a big ol' F**K YOU to the Collectors. They killed Garrus. And Thane. And Jack. But MOSTLY GARRUS.
Garrus Vakarian, Died in Action assaulting a Collector base: I hope my next playthrough treats you better.
Does anyone else get angry/depressed when they lose a comrade like Garrus or somebody in a game like Mass Effect? I mean, jeez, I yelled "Dammit, no!" when it happened.
