The player chooses one of six planes or can opt for a random choice. The first four stages are in random order, while the last four are sequential. Players collect weapon powerups, bombs, and gold bars for points. Each plane has a unique "supershot" which is charged by damaging enemies and fired by holding then releasing the fire button. Supershots can be stored, although the number varies from plane to plane. Using a bomb results in a large friendly fighter swooping onto the screen and blocking shots while returning fire for a few seconds.
After the player beats the final boss, the game starts again from the beginning, albeit at a much higher difficulty level. All level are similar to the ones in Strikers 1945 II. Only one of the four bosses that are randomly chosen and the sixth boss is changed.
In 2008 Gamewave magazine has confirmed that Strikers 1945 Plus will get a PSP release for February 2009. PM Studios, the publishers of DJ Max Fever, published the game as a downloadable game on July 30, 2009 in the United States.
