Can doing this glitch, mess up your console? (Link)

Not really.. I doubt any ingame glitch can effect your console tbh. If you get caught cheating due to an ingame glitch chances are your might get reported and banned from the servers. That video dates back to 2009, might of been fixed already. No harm in trying it out with a friend or somethin.

you know what that tells me that it is possible to make huge maps in COD so why dont they do that.
