Square Enix has launched its Tomb Raider Scavenger Hunt, a series of weekly trivia and photo challenges, that reward participants with in-game DLC and other special prizes.
The Tomb Raider Scavenger Hunt began on December 18th and is available on mobile (iOS, Android, Windows Phone) / tablet devices and online. It will be available until the game's release on March 5, 2013.
In order to participate in the Hunt, you must pre-order the game. By joining the Scavenger Hunt you have the chance to unlock up to five in-game DLC items, along with physical prizes like Tomb Raider-themed consoles and life-size statues of Lara Croft. The first runner-up winner will receive a Tomb Raider-themed all-terrain vehicle. The grand prize winner, however, will win a trip for two to Fiji with hotel and airfare included, along with activities true to the Tomb Raider experience (minus the shipwreck I hope).
