Call of Duty: Ghosts will be promoted with a limited-time free multiplayer demo on Xbox Live this weekend.

Polygon reports the demo will be available on both Xbox 360 and Xbox One, and is the first time the franchise has offered such a trial on Xbox although several Call of Duty Steam trials have occurred.

The taster will be available from 1:00PM ET on March 7 through to sometime Monday, and will include three maps (Strikezone, Warhawk and Prison Break), three competitive multiplayer modes (Search and Rescue, Domination and Team Deathmatch) and the co-operative Extinction mode, Point of Contact.

Ah of course. Activision and MS are best of friends, shame it's not on the PS3/PS4

However, Friday night I'll be on my xbox 360, so no doubt will be giving this a blast.
