gradius2: MAME ROM Information.


History:

Gradius II - GOFER no Yabou (c) 1988 Konami.


The third game in Konami's renowned "Gradius" series; the prequel being "Gradius" (known as "Nemesis" in Europe) and a spinoff called "Salamander" (also known as "Life Force"). Gradius II strictly adheres to the shoot-em-up template set out by its hugely successful predecessor, the game eschews the sideways/vertical scrolling alternate levels of "Salamander" and opts instead for "Gradius" sideways scrolling-only mechanic. This game is rightly considered to be one of the most demanding and difficult shoot-em-ups ever released.
