Cool It achievement glitched? Spoiler inside.

I helped Dr. Matthews by turning off the 3 valves outside the observatory. Now I'm at the drive-in. No achievement - I'm assuming I should have it by now? The achievement description makes it sound like I should have.

Spoiler Alert.

You have to replay the section at the Observatory. In a 2nd time

[NativeMilk]

You mean I return to the observatory as part of the story and get it then?

[Agusta1]

Yeah. Pretty Much

[NativeMilk]

OK thanks.

EDIT: I just checked your gamercard. You haven't unlocked it yet. How do you know?

People are so impatient sometimes! You've not finished the game yet and you're presuming it's automatically glitched! Just keep on going, I'm on my second time at the observatory at this very minute and haven't got the achievement yet ;)

EDIT: Just got it.

[Agusta1]

OK thanks.

Because I'm up to the 2nd part. But I'm too tired to play it up to the end.

Keep playing, you'll unlock it.

[NativeMilk]

Got it now. Thanks guys.
