Four maps (Atacama Desert, Isla Inocentes, Nelson Bay, Valparaiso) have been converted to support the single-squad gameplay against AI enemies, in an approximation of the game's "Rush" gameplay mode. The DLC has previously been available as paid content on the PlayStation 3 and Xbox 360 versions of the game.
A trailer for the mode can be viewed below.

While this serves as a confirmation that the mode will hit the PC, details are still light. Shacknews has reached out to EA to find out if "Onslaught" will be paid or free on the PC and if dedicated servers will be required or if the game now supports peer-to-peer networking. A response was not available at this time.Thanks to Shacknews member Hemtroll for sending this tip!
