A year-long global war between the World Alliance and the World Order Reorganization Front has ended with planet Earth in peril. As a result of resentment and distrust, the World Alliance has begun to split, and the seeds for a new global war are being planted. In the midst of this epic war, Lethal Skies II puts you in command of an Air Force, including 19 of the world's most devastating fighter planes. Through 20 missions, you'll be able to switch control to other vehicles such as jets, tanks, battle mechs, and submarines, and you can even switch roles and become the enemy.
