Call of Duty: Ghosts Onslaught DLC free to try this weekend, but only on Xbox One and 360

Call of Duty: Ghosts will offer up its recently released Onslaught DLC for free this weekend, offering players on Microsoft consoles a chance to sample its four extra maps without having to pay anything. Activision would probably quite like it you did purchase the pack eventually, however.

Activision will release a trial version of the Onslaught DLC as a download on Friday, March 21, which will be playable until Monday. It contains all four of the new maps-- Fog, Bay View, Containment, and Ignition--and the Maverick dual assault rifle/sniper rifle.

Fans of the co-op alien-fighting Extinction campaign, such as GameSpot's Shaun McInnis, will also be able to play the first chapter of the four-part DLC campaign.

The offer is only available for Xbox One and Xbox 360, as Activision and Microsoft have an exclusivity deal. Activision says other platforms will get a shot at the free weekend at a later date.
