While the beta has been a big success on Steam and other platforms, it hasn’t been a perfect beta. Some server issues have left players unable to play. More oddly, Back 4 Blood closed beta players began running into zombies that seemed to be yelling the n-word.

WB Games explained to Kotaku that zombies weren’t screaming slurs at folks. Instead, two sound files were playing at the same time and creating the offensive-sounding word by accident. WB Games hopes to have the issues fixed by the time the game launches in October.
