Call of Duty: Warzone players have been using a companion app to cheat the battle royale's competitive matchmaking system. The creators of Warzone Companion, an app that helps players avoid cheaters by displaying K/D ratios before a game, was forced to adjust the stats it displays in pre-game lobbies. Some players were using the stats to back out of lobbies that had players with high K/D ratios.

"Cheaters are one of the worst problems of Warzone and online gaming overall," Dmitry Shymko, the CEO of COD Stats, the company that runs the app, told Eurogamer. "We wanted to help the community and highlight those players that are having extremely high metrics in their previous matches and at the same time give an instrument for players to see that they just might die to the lucky shot."

The app was designed to help players check pre-game lobbies to see if anyone had stats that are only attainable through cheating. Players ended up using the app to avoid unfavorable lobbies altogether. COD Stats issued a patch that now displays the K/D ratio information after the pre-game warmup, among other changes, earlier this week. Now the app can no longer serve its original purpose of helping players avoid Warzone's rampant cheating problem.
