Regardless of how you feel about the ubiquity of the battle royale genre, Fortnite seems to be the battle royale shooter, as it pulled in $296 million digitally worldwide in the month of April, according to SuperData, a research firm that tracks the digital sales of games across console, mobile, and PC. That's a 33 percent increase from the $223 million Epic's shooter reportedly made in March.

This makes Fortnite the first and fifth highest grossing digital game on console and PC worldwide, respectively. The other big battle royale shooter, PUBG Corporation's PlayerUnknown's Battlegrounds, claimed the ninth spot on PC but didn't rank anywhere in the top 10 on console. Though both games have mobile ports, neither placed in the top 10 in that market either.
