Super Contra - Alien no Gyakushuu (c) 1988 Konami.
This sequel to the 1987 original is set during the month of December in the year 2634. A disturbing distress signal from General Hal - who was on his way to South America in preparation for the GX Army's 7th military maneuvers- is received, reporting that the GX Army has suddenly revolted. The top branch of the federation forces calls in Bill and Lance to investigate the situation.
They arrive at the base ruins, only to find out that the GX Army's troops were being possessed by the same kind of mutated creatures they fought at Galuga in the original 'Contra'. The situation is worsened by the fact that Bill and Lance will be killing their former comrades-in-arms.
Super Contra plays identically to its predecessor, with the usual mix of run-and-gun gameplay. The main difference was that the into-the-screen stages of the original Contra were replaced by overhead stages. In addition, weapons were now upgradable and represented by the actual guns themselves as opposed to the letter icons of the first game. Players have also gained the ability to duck underwater to avoid being shot. There are a total of five levels, many of which have sub-bosses.
Super Contra's weapon Power-ups are as follows :
* Machine gun.
* Grenade launcher.
* Spread gun.
* Laser.

>>> TRIVIA
----------
Released in January 1988.
The subtitle of this game translates from Japanese as 'Alien's Counter-attack'.
This game is known outside Japan as 'Super Contra'.
Note : The kanji on the title screen actually reads 'Kon To Ra', meaning 'Soul Big Dipper Gauze'. This is an example of 'gikun', where Japanese artists use the phonetic value of a character to determine the game's name and not the meaning of the character itself.
King Records released a limited-edition soundtrack album for this game (Music From Super Contra & AJax - K30X-7702) on 21/03/1988.
