Space Guerilla1979

Vulcan Venture (also known as Gradius II: Gofer no Yabo) is a side-scrolling shoot ’em up developed by Konami and released in arcades in 1988. Players control the Vic Viper spacecraft as it battles the Bacterion Empire, now led by Gofer. The game builds on the original Gradius by retaining the power-up bar system while introducing selectable weapon configurations and expanded abilities such as different missiles, double, and laser options. It also incorporates elements from Salamander (Life Force) and introduces a stage focused entirely on consecutive boss encounters.

Shoot aliens as they move across the screen. Shoot the spaceship for extra points. Choose one of three games. Space Fever is a 1979 arcade game by Nintendo R&D2. Some sources claim that Ikegami Tsushinki also did design work on Space Fever. It was released in both monochrome and color versions. The gameplay is similar to Space Invaders, which had been released by Taito in 1978. It was distributed by Far East Video. The gameplay of Space Fever is reminiscent of Space Invaders (1978), where the player controls a laser cannon situated at the bottom of the screen and must defeat waves of enemy aliens. The aliens are arranged in rows and slowly move to the edge of the screen, before descending and continuing in the opposite direction. As more aliens are defeated, they increase in speed. A UFO will occasionally appear towards the top of the screen, which can be shot down for bonus points. There are three game modes that change the way the aliens move; the first presents two formations of enemies that move in opposite directions, the second continuously adds additional rows of aliens, and the third is functionally identical to Space Invaders.

A special version of Space Fever called SF-Hisplitter was released the same year and features aliens that are double the width of the standard variety, which can either be destroyed completely or split into two smaller aliens depending on where they are shot. This version is in color, and the shelter blocks are visually distinct from the monochrome version.

Space Armada is a clone of the game Space Invaders. Rows of bomb dropping aliens are invading your home planet, and you need to protect it! You control a laser gun at the bottom of the screen; your goal is to earn as many points as possible by destroying the waves of attacking aliens at the top of the screen. The aliens march steadily downward, and if they reach the ground or you run out of laser guns, the game is over. When all aliens in a wave are destroyed, you move on to the next, more challenging round. From time to time, a flying saucer will pass by at the top of the screen which can be shot for bonus points.
