But although Modern Warfare 2’s release is a historic one, that doesn’t mean that it’s perfect. There are many, many issues plaguing the game currently, especially if you’re on the online multiplayer side of things. Though, you can find easy ways to fix a handful of them. And if you’re having an issue with the “exe/bad_challenge” error, we can actually help out with that one. Let’s explain!

How to Fix “exe/bad_challenge” Error in Modern Warfare 2

When it comes to issues like errors or bugs in games like Call of Duty: Modern Warfare 2, sometimes it can be an issue too big for players to fix on their own which can totally keep players out of the action. Fortunately, “exe/bad_challenge” error that players have been running into, in most cases, can be fixed by the player with only a couple of steps standing in between them and the action. Here are some remedies you can use.

Close and Restart Your Game

The first thing that you should always try is to simply fully close the game a try giving it a fresh boot. If you leave the game running on your console when you put it into power-save or safe mode, it has more of a chance to encounter errors when you come back to it.

Restart the Console From Scratch

If that doesn’t work, try restarting your console instead. Again, while things like power-save or safe mode are great for gamers as it helps to run updates when the console is asleep, they can sometimes run into more issues since they’re not running a fresh boot. Restarting it entirely could help right off the bat in most games, not even just Modern Warfare 2.

Check for an Update

If neither of those methods works, try checking your game to see if it needs an update or has one queued up already. Running the game whilst it needs an update is one of the most probable reasons for an issue like this error.

Uninstall and Reinstall the Game

If all else fails, it’s time to uninstall the game completely and reinstall it. It may take a while to get it downloaded again, but at least you’ll be able to play without issue.
