Beginning right now, May 23, and running through May 27, you can play the multiplayer portion of Call of Duty: Ghosts for free. The catch is that this is only for the Xbox 360 and Xbox One platforms.

This is, what, at least the second or third time they've given a free weekend for this game on the Xbox platform alone. There were other free weekends for other platforms tossed in as well. So, I can only assume that the string of free weekends means that the game is doing quite well on all platforms.

If you really need any additional info, you can get it at the Call of Duty site.
