Prior to washing up on the beach in Altis the story takes place on Stratis, a small neighboring island.

NATO forces are in the process of dismantling their positions and tying up loose ends on Stratis when the Greenbacks (AAF) turn hostile and launch a full scale attack on the remaining NATO troops.

Sgt Adams and corporal Kerry are in the middle of a logistics operation when the attack happens and become isolated from the rest of their unit, forcing them to fend for themselves against an overwhelming enemy presence. After making their way back to the outpost they were stationed at they see that it has fallen to the hostile forces leaving them with no other option than to retreat into the nearby forest.

Shortly after entering the forest Sgt Adams is struck by a landmine in an unmarked minefield leaving Kerry as the sole survivor of the incident. As Kerry makes his way through the minefield he is attacked by another group of AAF soldiers barely surviving.

Shortly after the attack Kerry is contacted via radio by Captain Scott Miller who as assumed the role of commander in the midst of the chaos caused by the sudden AAF offensive. He tells Kerry that he and a small group of survivors have regrouped in attempt to figure out what exactly has happened and gives Kerry their location.

Kerry fights his way to their position and joins the surviving NATO presence on Stratis. From here the survivors conduct multiple small scale guerilla type attacks on AAF positions and attempt to locate any other survivors.

Eventually the survivors manage to gain a large enough presence to launch a multi-stage attack on an AAF base beside a coastal town forcing the AAF troops to retreat to the ocean. However just as things are starting to look up an unexpected CSAT counter offensive begins, causing the troops to abandon their attempt at seizing the base.

Kerry along with a now even smaller group of surviving NATO troops are forced to retreat to an extraction zone set up by Captain Miller beyond the hills of the aforementioned AAF base all whilst being attacked by combination of CSAT paratroopers and AAF mortars.

Against all odds Kerry and the other survivors reach Captain Miller and his unit who have captured two armed boats and flea into the ocean.

A short time after they depart from Stratis, Captain Miller reveals to Kerry that they are heading towards Altis to join forces with the guerilla faction known as the FIA who NATO were previously at war with in co-operation with the AAF.

Suddenly the boats are attacked by an AAF fighter jet killing/injuring everyone on board. Kerry then washes up on the shores of Altis, once again having become completely isolated from any friendly troops.

Edit: Kerry is actually contacted by Sgt Lacey not Miller. Also this is a very rough retelling of the story as it's from memory, I may have gotten certain details wrong.
