Popular games for collection Salamander

Life Force is an action-packed shooter where there are six levels which alternate between side and vertical scrolling, each of them ending with a powerful guardian. Throughout the game, destroying certain enemies will release power ups which can be used to equip your ship with more powerful weapons, extra speed, and shields. Gameplay is for one player or two players simultaneously.

Salamander is a scrolling shooter arcade game released by Konami as a spin-off to Gradius. It introduced a simplified power-up system, two-player cooperative gameplay and both horizontally and vertically scrolling stages. Some of these would later become the norm for future Gradius games.

Like the original Salamander, and as opposed to the Life Force releases, Salamander 2 abandons the selection-bar based power-up system, in favor for a simplified system that focuses on powering weapons up based on specific icons. For example, the player cannot increase his ship speed until a speed icon is picked up; additional speed icons further increase the ship velocity. Several weapons, when additionally upgraded, turn into a 'super' weapon for approximately ten seconds. If the player has the ripple laser, and then gets another icon for it, the player will receive the high-powered Buster ripple for a short period of time. Options have been slightly changed with the arrival of 'option seeds', which are small options that orbit the ship firing only the basic initial shot. Two option seeds can combine into one full option. Moreover, options can also be sacrificed to utilize a short-term homing beam weapon. Several enemy bosses typical to Gradius games return, including the Brain Golem (the first level boss) and the Tetran (the second level boss). There are a total of six levels. Since the game is similar to its prequel, Salamander 2 does not use the Revival Start feature from Gradius (which pushes the player back to a pre-determined checkpoint if a life is lost), many people consider this title to be easier than other titles in the Gradius series due to this. Once the game has been completed, it starts its second-loop at a much higher difficulty. The music is also changed to remixed versions of Salamander's music in some stages. The first player's ship is called Vic Viper while the second player's ship is Super Cobra.

Konami later released an enhanced version of Salamander in Japan in 1987 bearing the American title of Life Force which further fleshes out the organic motif. All of the backgrounds and mechanical enemies are completely redrawn and given organic appearances. The power-up system was also modified, with the Japanese Life Force using the same power-up gauge as the original Gradius. Some music tracks have been completely changed for this release and the power-up gauge is arranged differently for both players.

The Japanese and European versions are nearly identical, but the American version changes the game's plot by adding an opening text that establishes the game to be set inside a giant alien life-form which is infected by a strain of bacteria. Stages that feature starfield backgrounds were changed to the web background from Stage 1 to maintain consistency with the organic setting of the plot. The power-ups are also given different names, with the "Speed-Up" becoming "Hyper Speed", the "Missile" becoming the "Destruct Missile", the "Ripple Laser" becoming the "Pulse Laser" and "Force Field" becoming the "Shield". Narration is added to the beginning of each stage, detailing the area of the alien's body which the player is currently inhabiting such as "Enter stomach muscle zone" or "Bio-mechanical brain attack".

Salamander III is the newest addition to the Gradius series, a legendary pioneer in the side-scrolling shooter genre, and comes with the original arcade versions of the previous games.

The MSX port of Salamander (沙羅曼蛇, Saramanda) is significantly different from the original and any other ports. New to this port is a graphical introduction that introduces human pilots for each ship, as well as names for each stage. The levels are notably longer than the arcade original, and the player is forced to start from a pre-defined checkpoint upon death of either pilot, instead of starting where he left off. After level two, the player can choose the order of the next three stages. In addition, the player can collect "E" capsules by destroying certain enemies. Collecting fifteen will permanently upgrade one of the available weapons on the power-up bar. Some weapons allow the player ships to merge, one player controlling movements and the second player controlling weapons. Instead of the Vic Viper and the Lord British Space Destroyer, the ships are known as the Sabel Tiger and the Thrasher; piloted by human characters named Iggy Rock and Zowie Scott. The story takes place in the year 6709 A.D and has 2 different endings. The MSX version was re-released for the Wii's Virtual Console in Japan on January 12, 2010. It was later released for the Wii U's Virtual Console on July 20, 2016. They were also made available for the Project EGG on Windows Store on May 19, 2015.
