SAN FRANCISCO - March 21, 2007 - Leading casual game publisher PlayFirst today announced the launch of its new title, Mystery of Shark Island™ - a hunt-and-seek adventure set amidst an alluring beachcomber backdrop. The game is now available to download for both the Mac and PC at http://www.playfirst.com/game/mysteryofsharkisland.

"Mystery of Shark Island tempts everyone's inner beachcomber," said Kenny Dinkin, Vice President and Executive Producer, PlayFirst. "It weaves together a new kind of hunt-and-seek by innovating on this popular type of game and combining it with a riveting storyline that takes its cues from some of today's most exciting prime-time television dramas. MSI immerses players in a suspenseful story, wrapped with gorgeous animations and eye-popping gameplay all set to a soothing yet mysterious cinematic soundtrack."

In the game, players transport themselves onto the sands of Shark Island - an arcane archipelago yielding the mysterious relics of an unknown civilization. To solve the riddle players must scour each sandbar or tide pool and collect sea shells, rocks, gems and artifacts hidden in the sand. Picking up the right treasures will start to unravel the island's mysterious past, but all progress could be lost with the next incoming tide.
