Air Strike 2 gives you brand-new units--armored vehicles, heavy helicopters, submarines, destroyers, carriers, and speedboats--to complete missions over water, desert, mountains, and densely populated areas. While the enemies have become tougher, you can now upgrade and modify weapons yourself to meet the challenge. You can test your pilot skills in helicopter duels across new terrain types and environments. Plus, after passing a level and killing its boss, you can fly through bonus levels to empty your adrenaline tanks and release the unused rage.
