Darksiders 2 is coming out soon on consoles & PC, and THQ has launched a mobile app to help get people involved with the game. Darksiders 2: Soul Harvest integrates that most unholy of social networks, Facebook, to help players get rewards and potentially win prizes.
Users harvest souls from nearby real-world locations based on how many people have checked in to that location. The player can harvest souls from locations every 10 minutes. Harvested souls go toward a counter that will unlock extra content, such as backgrounds, a mini-guide from Prima Games, and a copy of the Darksiders digital comic. However, to unlock them, not only must the user harvest the prerequisite number of souls, a community total number of souls must be harvested as well. Eventually, an exclusive piece of in-game content may be made available once the community unlocks it.
Users are also entered into a contest to win prizes such as a full-sized Death Scythe, a custom Darksiders 2 Xbox, and even the ultimate prize: a trip for 2 to Cancun with a visit to the Chicxulub crater in December 2012 to potentially see the end of the world.
