Spacetime Studios’ Call of Champions joins the mobile MOBA fray on iOS

The day of the multiplayer online battle arena (MOBA) in mobile gaming has arrived. So says Spacetime Studios, a startup that is releasing Call of Champions today after more than two years of development.

Like Super Evil Megacorp’s Vainglory that preceded it, Call of Champions is a big test as to whether the lucrative MOBA category on the PC — played by more than 140 million people a month, according to market researcher Super Data — will spread to mobile, which has become one of the fastest-growing categories for games, with expected revenues of $30 billion in 2015.
