New 4-player Shmup for Arcades: P-47 Aces Mk.II (exA-Arcadia; Amusement Expo 2021)

https://arcadeheroes.com - While there are many fighters headed to the exA-Arcadia system, it has a lot of shoot 'em ups (shmups or STGs) too. Here's one that will be exclusive to the system, a remake/major update to Jaelco's P-47 Aces. It supports up to 4-players and has adaptive difficulty to work for the needs of FECs while satisfying core players.
