Salamander, retitled Life Force in North America and in the Japanese arcade re-release, is a science fiction 2D scrolling shooter arcade video game by Konami.
Released in 1986 as a spin-off to Gradius, Salamander introduced a simplified power-up system, two-player cooperative gameplay (using two starfighters, the original Vic Viper and a new one called Lord British) and both horizontally and vertically scrolling stages. Some of these later became the norm for future Gradius games.
