Call of Duty players have become accustomed to a few nasty bugs over the years. However, none of them are more irritating than development errors.
A dev error is a game-breaking one for most players, especially when they're in the middle of a heater in Warzone 2 or a nuclear attempt in Modern Warfare 2 multiplayer.
A dev error makes the game unplayable, always seems to occur at the most inappropriate times, and generally destroys the squad's bonds for some time. Sadly, there isn't much to be done about them for the most part, but there are methods to try and minimize the issue as much as possible.
Here are the details on another CoD dev error, dev error 615.
In MW2, how do I fix Dev Error 615?
CoD's development error indicates that something is wrong on the game's side, so there's nothing you can do much about it until the game's designers provide a remedy.
Despite this annoying bug, there are a few simple methods you can perform on your end to ensure that you continue to play MW2 multiplayer, Warzone 2, or DMZ games.
Many CoD players have reported that dev error 615 occurs whenever they attempt to climb or hang from a ledge in MW2, Warzone 2, or DMZ. This is a very specific situation that may require a resolution in an Infinity Ward patch, but it doesn't hurt to ensure that your game and device are up to date.
Make sure your game is fully updated, first and foremost. This can be done by checking for updates on consoles or through the launchers where the game is played, like Steam or Battle.net. Updates are usually automatic, but try restarting your game and manually checking for an update.
If you're playing on a PC, it's always helpful to check that your operating system and graphics cards are up to date. Run Battle.net's "Scan and Repair" feature, or, in the worst case, restart the game completely to see if the error has been resolved.
If none of these general problem-solving techniques seem to work, then it may be time to sit back and wait to hear from the developers about a solution.
You may report an error on the appropriate Activision help and support channels, so that the developers may investigate the issue and find a solution for it.
