Confirmed. Trance Mission can be used to rack up play time, but the unlocks don't come until after you play another normal level. I left Trance Mission running for about four hours, then quit and nothing happened, but then I made another run at Area 5, and afterward I got the unlocks for five hours, six hours, seven hours and eight hours all one right after the other. I should have "Rezident" in no time.
As far as I'm concerned, Laser Assassin looks like it's the only really difficult achievement in the game. Everything else seems to unfold in a natural order once you figure it out.
