Early Jet Air Combat. MiG Alley Ace is a quick and easy jet air combat game, it is meant to cover air combat from 1945 to the start of the missile age. The game is based on Avalon Hill’s Mustangs game. MiG Alley Ace was created with a hex-mat and miniatures in mind, but could be played a regular hex-map with counters. A hex-map and counter-sheet have been included with these rules. You will have to mount and cut out the counters yourself.
