The document discusses how Epic Games used ClashMob challenges in Infinity Blade 2 to increase player retention and engagement on social networks. ClashMob challenges required thousands of players to collectively complete tasks to earn rewards. Players received bonuses for social actions like liking Facebook posts or retweeting tweets. This increased users' social interactions and improved metrics like the Facebook Engagement Index. The document also describes how the game integrated with social networks' APIs to support these social actions and monitor their effects on metrics like reach and impressions.
