The time is World War 2: The night sky enshrouds your ill-fated B-17 Bomber aka “The Zapper” like certain calamity. Your mission is to release a payload of bombs on a Nazi munitions factory, and remain airborne long enough to do so.
The clouds harbor flying demons, whose purpose is to destroy any and all allied planes with single-minded savagery. These sharp-toothed Bandits are all over the clock and coming for you. Stay alert. Stay alive. Stay aloft.
