The players control WWII planes in this 2-D vertically scrolling shooter. Missions are flown alternately in the clouds against enemy planes and over water where there player must also disable enemy ships. There are many different weapons available via power-ups.
Pressing both buttons simultaneously causes the player's ship to loop out of the 2-D action plane temporarily. This is very useful for getting behind enemy planes. Pressing Special calls up a special attack (lightning in the air, a wave over water), but also uses up the player's energy. The game is over when the player runs out of energy, but energy can be replenished via power-ups or for completing a level. Likewise, in two-player mode, players can share life energy by placing both planes over each other for two seconds.
