But the Parcel islands are in for a storm. The tides are changing, the clouds are forming, and a full on hurricane is headed for the battlefield. Battlefield 4's levelution on the Parcel Storm map was a brilliant idea with excellent execution. Levelultion was an idea DICE (BF franchise creators) had for the game. They thought they would put a spin their signature huge maps, by allowing an event to be triggered to changed the map entirely. Whether it be a hurricane, a flood, a collapsing building, or maybe even a blizzard, Battlefield has it all.
