(Originally released on the MSX console in 1987) Nemesis 2 (Gradius 2 in Japan) is a side-scrolling shoot-em-up. The gameplay is for the most part similar to that of Gradius. The player-controlled ship can alternate between three main weapons. In addition, special power-ups can be acquired. Boss battles are followed by optional mini-stages, which grant the player new weapons if completed successfully. (mobygames.com)
