You've Been Framed!

Agent Frank McBain is dead... but why did they pin it on you? You've just 96 hours to find out... crack an international spy ring... and prevent an INTERNATIONAL DISASTER!

You're American agent Mason Powers and you've just intercepted an ultra secret message about an international terrorist group. Just as you're about to brief CIA Section Chief, Frank McBain, everything goes black... and you wake up in a remote prison hospital in Turkey... with no memory of what happened and charged with the murder of Frank McBain!

Who set you up? Who is trying to kill you? And why do you feel such intense urgency? The Countdown has begun... and you'd better find the answers fast.

If you break out of the hospital you'll set out on an interactive adventure of intrigue and espionage taking you from Istanbul to Paris... with both agents and terrorists in hot pursuit. Interview different characters which converse, animate and respond (some actually talk!)... use your hand held computer to search for key evidence... gain valuable clues in realistic Motion Graphics flashbacks!

But can you complete your mission in time to avoid global disaster?
