Activision is hosting the very first Call of Duty multiplayer demo event this month, for Call of Duty: Ghosts. Basically you can try the game before you buy, at least for a limited time. Set to begin this Friday, March 7, the demo will run through Monday, March 10, and only on Xbox LIVE.
To be more specific, the Ghosts demo weekend will start at 10:00 A.M. PST on March 7 and presumably end a minute before midnight on the following Monday. Participants won't have access to all the content but still be able to experience a good chunk of the multiplayer. The three maps included will be Strikezone, Warhawk and Prison Break. The three modes available will be Search & Rescue, Domination and Team Deathmatch. For co-op fans, Point of Contact for Extinction mode will also be unlocked.
Activision and Infinity Ward will also host a free trial weekend for Call of Duty: Ghosts' first DLC pack, Onslaught, on March 21 via Xbox LIVE. The add-on was just released to PC and PlayStation consoles last week, a month after the Xbox release.
