Aces

Aces is a WW2 Shot 'em up inspired by 1942 and Sonic Wings/Aero Fighters for Android

From the Invasion of Poland to the Fall of Berlin and beyond, Aces features some forgotten and overlooked aircrafts such as the polish PZL P.11 and the french Dewoitine D.520 in a semi-historical journey through the Second World War in Europe.

This is an incomplete game: only 5 of the 13 planed missions are available. The game currently spans from September 1939 (Invasion of Poland) to September 1940 (Battle of Britain). The level backgrounds are mostly unfinished.

If you are wondering what the hell an Su-27 Flanker is doing during the Invasion of Poland, the game was supposed to have some Wolfenstein-esque missions after the Fall of Berlin with some time-travel shenanigans
