The Second Samurai is a beat-em-up developed by Vivid Image and Psygnosis and released exclusively in Europe for the Commodore Amiga (1993) and Sega Mega Drive (1994). It is the sequel to The First Samurai, a beat-em-up released for various home computers and the SNES internationally a few years prior.
You play as one of two Samurais (the 1-player mode has the male protagonist from The First Samurai only; the 2-player mode lets the second player control a new female Samurai). A and B both attack depending on what weapon you have equipped right now (only one at a time, some in limited quantities), what enemies/objects are nearby, and which D-pad buttons you are holding at the time. C jumps. A screen at the beginning of the game (also accessible from the Options menu) shows you what each in-game item does for you.
A Sega Mega-CD port was advertised, but never released.
