Play Call of Duty Modern Warfare 2 in its Original Language with this Fan-Made Mod
Resetting to a clean save, or clearing the game's temporary files and re-installing, should fix other Modern Warfare 2 errors that you might encounter. Just when you thought you'd seen everything that could go wrong with a video game, Activision decided to try and ban an in-game voice chat tool, which could quite easily have been used to talk to your co-op friends on your PS3 or 360. Thankfully, this idea has since been retracted, but there's still time to export your friends list and import it into Black Ops, so you can keep some distance from your European friends and play with some big boys over in America.
Call Of Duty Modern Warfare 2 English Language Patch
From downloading the game, purchasing it or downloading the IOS version, the first thing you will want to do is patch up any errors that you run across. You do this by going to the main menu and clicking Options. In the Options screen you should be able to select the language option, if there is one. However, there are other options here as well, namely the resolution and audio settings. It may be easier just to delete the default file that came with the disc and reinstall the game again and make sure that you set the resolution to 1280 x 720 and the graphics quality to High, as this generally fixes most Modern Warfare 2 error codes.
Using your PS3 (or Xbox 360) game's network, check for any new messages and resolve the contacts you can. The first time you do this you'll probably find that a number of players have joined your team and you'll need to issue them an invite. After that, you'll be able to join their games or be able to do it yourself using the console. Some multiplayer modes, such as the Black Ops round for Call of Duty: Black Ops, might require a degree of teamwork to work, so only try to play the game in its entirety with friends who you know you can trust. Whatever you do, make sure you use enough different Antennas and Don't Spook Your Team-ups to reduce the likelihood of getting nagged by your team.
