What Gigas did to Sanctuary is what they wanted to do to Caldera. The thought of them getting away with that for as long as they did makes me want to see red. Taking away someone's freedom is pretty unforgivable in my books.

[Among other reasons.]

Also, I don't know if you were at that mission briefing, but I've been held in Gigan captivity before. It's not anything someone should have to go through. I want to do what I can to stop that from happening to anyone else.
