SE3K Survivors Experience 3000

N-Sub

Compile, Sega · 1986

Sega's 1980 cabinet, adapted by Compile. A submarine attacks the ships on the surface with torpedoes fired upward, while depth charges come down and other submarines cross the screen at its own depth — two axes of attack and defence at once, which was more than most 1980 games asked.
