Welcome to the most desirable group on Steam...

The hunt is over, you have found the most desirable Steam group on Earth.
You want to join, you want to NOW.
BUT WAIT!
You must first help other people get what they desire most in the rather excellent game 'The Cave'. Return to me when you have every achievement in this game for exclusive entry into this highly desirable group.
Have fun spelunking!
-Bales, Officer of Noble Sentient "The Cave"

Note: Double Fine employees may enter this group without all achievements, because they are Supreme Officers of The Cave and I have no power over them.
