In a nutshell, you get a group of people together, load up the app, select a category, and then hold your iPhone (or iPad) up to your forehead. From there, you've got 60 seconds where a word will appear on the screen, everyone else shouts clues, and you try to guess it. If you get it right, you tilt your device down, if you can't get it and want to skip you tilt up. It sounds basic, but even beta versions of the game that randomly would appear at bars and restaurants of GDC was a ton of fun.The game also utilizes the front camera of the iPhone to record friends trying to act out whatever the word is. Players can then share those videos on Twitter or Facebook, and also submit them to be featured on The Ellen Show.
Heads Up! is available on the iPhone and iPad for $0.99. [Direct Link]
