The first map pack for Call of Duty: Ghosts will release on PlayStation 4, PlayStation 3 and PC on February 27, Activision has announced.
Onslaught bundles in four maps - Fog, BayView, Containment and Ignition - along with a brand new chapter in co-op mode Extinction.
A new dual-purpose weapon, the Maverick, is also included and able to switch between functioning as a sniper rifle and assault rifle.
The pack will be available for £11.59 and is provided at no extra charge to Season Pass holders.
Onslaught first launched on Xbox One and Xbox 360 last week, although doesn't appear to be coming to Wii U.
