Did you guys ever play the first Homeworld game, after reading the backstory in the manual?
Do you remember the mission, Return to Kharak?
I replayed that damn mission, over and over again, until I saved every cryotray.
During Homeworld: Cataclysm, the Taidan convoy missions, that first audio of them being subverted, replayed the mission over and over until I saved every single one.
