Released in June 1995.

The game forbids the initials 'SEX' on the high score table. If you try, it gets changed to a smiley, and 'THAT IS WRONG' appears.

Pony Canyon / Scitron released a limited-edition soundtrack album for this game (Strikers 1945 II, Strikers 1945 - SGCD-0001) on 20/12/1997.


* Unlock Extra Maintenance : if you hold Test Button + PL1 Button 1 during boot, you get extra options in the test menu. A level skip, BG test usually etc...

* Sexy Pilots Images & Names : if you make a perfect score, you can see how the sexy pilots look and what their names are. In practice, this means getting three gold medals at the end of each stage (for time, accuracy and completion). This should be done in the first loop of the game, the pilot of the plane you chose will be seen at the end of this first loop. Two pilots will be seen if it's a two-player game. The pilots can also be seen in the Extra Maintenance menu.
