Darksiders II is set to be released in less than a month and THQ revealed earlier today that they have just released the “Darksiders II Soul Harvest” app on the App Store in the US and Canada. The free app allows users to “harvest the souls” of others who check into nearby locations on Facebook. App users also can enter to win daily Darksiders II prizes with a chance to win a “Trip to the End of the World.” Soul Harvest users will compete with their friends within North America to be the top harvester via an in-app leaderboard. Fans also will collect reward tokens as they reach new soul-harvesting thresholds, unlocking bonuses such as an in-game weapon, the first issue of the Darksiders digital comic, mobile backgrounds and access to trailers and other footage from the game. In addition to the exclusive in-app items, users have the chance to win daily prizes, such as a full-sized replica of Death’s scythe from the game. Daily winners are automatically entered into the grand prize drawing for a trip to the Yucatan Peninsula, the seat of Mayan civilization and home to the Chicxculub crater, purportedly where the asteroid struck that caused the extinction of the dinosaurs. The Soul Harvest app has been released in partnership with Best Buy, which is supporting it with in-store and online marketing activity. As part of the partnership, players who “reap” souls that have checked into Best Buys receive a bonus to their score. “The Soul Harvest app is a great way for Darksiders fans to connect with the game’s fiction and interact with each other,” said Jim Huntley, vice president of global brand marketing, THQ, Inc. “The app offers some awesome rewards for fans as they reap their way through the last few weeks before Darksiders IIlaunches.” Darksiders II follows the exploits of Death, one of the four horsemen of the Apocalypse, in an action-packed tale that runs parallel to the events in the originalDarksiders game. This epic journey propels Death through various light and dark realms as he tries to redeem his brother WAR, the horseman blamed for prematurely starting the Apocalypse in Darksiders.
