A free trial for the first part of the Extinction saga for Call of Duty: Ghosts will be available later tonight in the EU PlayStation store until Monday. Onslaught will have four new maps - Fog, Bayview, Containment, and Ignition, as well as a new weapon to try out.

Fog will be set in a camp near a like for a bit of creepiness while Bayview will be a Californian boardwalk meant to cater to snipers by offering various vantage points, but will also have buildings to traverse through for close-range combat. Containment’s focal point will be a bridge in the center of the map and Ignition will be modeled after Scrapyard from Call of Duty: Modern Warfare 2.

The new weapon that will be introduced is the Maverick, a combination of an assault and sniper rifle with an advanced scope. PlayStation Plus members will also be eligible for an additional 20% discount off the PS3 version of the base game as well.
