Twitter used to be a simple tool for people to tell their friends when they're in the bathroom. Now video game companies consider it a legitimate way to communicate with gamers. Infinity Ward is now accepting suggestions for Call of Duty: Modern Warfare 2 via its Twitter page.

If you've got a gameplay request for MW2, visit this page and send a reply. Just be sure to tag it #mw2. Keep it short and snappy too, because it'll probably get pushed off the front page quickly by the flood of suggestions coming in.

Modern Warfare 2 is slated for a holiday 2009 release.
