Synopsis :
Salamander (沙羅曼蛇サラマンダ, Saramanda), retitled Life Force (ライフフォース, Raifu Fōsu) in North America and in the Japanese arcade re-release, is a scrolling shooter arcade game by Konami. Released in 1986 as a spin-off of Gradius, Salamander introduced a simplified power-up system, two-player cooperative gameplay and both horizontally and vertically scrolling stages. Some of these later became normal for future Gradius games.
Salamander was followed with a sequel in 1996 titled Salamander 2.
The first player controls Vic Viper and the second player takes the reins of debuting spacecraft Lord British, which is sometimes referred to as “Road British” due to the ambiguity of Japanese-to-English romanization. The game features six stages which alter between horizontal and vertical scrolling.
Players are allowed to continue from where they leave upon death instead of being returned to a predefined checkpoint as per Gradius tradition. There are no continues in single player mode, and two in the two-player mode. The number of continues can be changed through DIP switches. The player gains power-ups by picking up capsules left behind by certain enemies, as opposed to the selection bar used in other Gradius games. However, the Japanese version of Life Force keeps the selection bar.
Many of the power-ups can be combined. For example, an option fires a second (or third) salvo of missiles or ripple/plutonic lasers if these power-ups have been attained. The ripple and laser, however, are mutually exclusive. The only power-up that can survive the ship’s destruction is the options (called “multiples” in the English release), they followed the exact flight path of the player’s ship and fired when they did, but were otherwise invulnerable. Upon the ship’s destruction, the options float in space for a brief time before disappearing; the new ship can grab and retain them.
