If you’ve spent time playing Infinity Ward’s previous game, Modern Warfare 2, chances are that you, or someone you know, has landed in a ‘modded lobby’. Now, unfortunately, these modded lobbies have started to pop up in Modern Warfare 3.
In these modded lobbies you could run into things like people with unlimited ammo, god mode, speed hacks, and even ‘walking’ IMS’s, AC130′s and Reapers (see video embedded below)! Although some may find it annoying getting raped by people that your bullets do no damage to while they shoot you with AC130 rounds, they won’t effect you like landing in a ‘de-rank’ lobby!
Should you land in a de-rank lobby you will lose all of your progress. Everything! Not only will you get put back to rank 1, you’ll lose all of your Emblems, Titles, and everything else you’ve unlocked. Gone. Leaving all the time you’ve spent on the game wasted.
The best way to avoid landing in these modded lobbies is to not accept game invites or join Private Matches from any player you don’t know and trust. Infinity Ward are aware of the issue and are no-doubt working on a patch to fix things up.
