In Acrophobia, players compete to see who can create the most creative phrase (or "acro") based on an acronym - three to seven letters - that the game presents to them. (A possible "acro" for DTA, Berkeley suggests, would by "Don't Trust Anybody," for example.) Players vote on whose acro is the best.
Version 1.2 of the game adds special interest rooms and changes the game's prize and point structure slightly (for instance, players who vote for the winning acro will now receive a Voter's Bonus Point).
