Control your Haunebu II and defeat the RAF! Use A/D to control left/right guns, W for upward firing gun, and arrows to move. Don't crash into the ground or enemy planes.
The Haunebu is a hypothetical German flying saucer that many believe was developed during the closing months of WW2. There was definitely research in circular wing crafts(like the Sack AS-6) but it is unclear if these aircraft were actually designed, or simply made up. The Haunebu II is the second development of these crafts, featuring a large main turret atop the cabin and four turrets underneath. It is unclear if it would have been a fighter, ground attack aircraft, transport or even some kind of flying artillery platform. It probably never existed at all. It definitely wouldn't fly. And it definitely was not built from alien tech in a secret base in Antarctica where Hitler escaped with his ET allies. That's crazy. Sorry if you believe that and I offended you, but seriously, It's crazy.
