Set in the not-too-distant future on an Earth devastated by the effects of global warming, Lethal Skies puts players in the role of an elite pilot flying for an alliance to save civilization. Players choose from among the most advanced fighter jets in the world, taking flight on numerous air-to-air and air-to-ground missions that span the globe. Lethal Skies includes accurately reproduced fighters such as the F-15, F-16, F/A-18, and F-22, as well as "black program" futuristic prototype jets that can be unlocked through gameplay. Pilots are propelled through cooperative and competitive missions to take on bombers, fighters, attack helicopters, and other enemies in a progressive series of attack and defense scenarios. With stunning 3-D graphics not typically found in flight simulation games, Lethal Skies delivers a heart-pounding experience.
