Salamander 2

Salamander 2 (沙羅曼蛇2 Saramanda Tsū?) is a scrolling shooter arcade game developed by Konami in 1996. The game is a direct sequel to 1986's Salamander and is part of the long-running Gradius series. The game is notable as it is the first in the Gradius series to incorporate three-dimensional graphic elements into its base of 2D graphics. It retains all the characteristic elements of its predecessor; two-player simultaneous gameplay, similar enemy and bosses, and inclusion of vertically-scrolling levels.
