Kixeye (stylized as KIXEYE, formerly known as Casual Collective) is a San Francisco, California-based developer of online strategy and combat games with over 5 million monthly active users. It creates games for competitive gamers and its titles Backyard Monsters, Battle Pirates, and War Commander prominently feature "explosions and gore and mayhem". Its real-time strategy game Backyard Monsters has had over 20 million installations. Kixeye expected to generate more than $100 million in revenue in 2012. Developers David Scott and Paul Preece began Kixeye as Casual Collective, where they developed 13 Flash games. The developers wanted to "make games that we grew up playing and that we love playing." In mid-2009 when searching for new venues for their strategy games, Scott and Preece decided to take their Flash knowledge and move it to Facebook. After developing Minions on Ice and TSG: Missions, Casual Collective hired Will Harbin, the co-founder of Affinity Labs, as CEO and moved its headquarters to San Francisco, where they developed Desktop Defender, a Tower Defense game for Facebook. After its release in December 2009, the game reached 675,000 monthly active users and produced more revenue in one day than their previous games made in one month.
