Front Line, released in arcade in 1982, is a military-themed run-and-gun shooter. The 'AA1, 4 PCB version' specifies the specific hardware version. The gameplay focuses on navigating warzones and eliminating enemies. The use of multiple PCBs (printed circuit boards) suggests a complex hardware setup possibly supporting higher resolutions, more advanced graphics or sound capabilities compared to simpler arcade machines.
