The year is 2142 and the dawn of a new ice age has thrown the world into a panic. The soil not covered by ice can only feed a fraction of the Earth's population. The maths is simple and brutal: some will live, most will die. In Battlefield 2142, players choose to fight for one of two military superpowers - the European Union or the newly formed Pan Asian Coalition - in an epic battle for survival.
Sunken City map.
Sunken City is an island with, of course, a sunken city in it. There are many open areas, which is ideal for aerial as well as ground combat.
This map works in coop, conquest. It hasn't been tested yet in multiplayer, so it may or may not work in it. There is no readme in the file, but there is one below that was sent in separately.
