Description

Geimos is an arcade style space shooter where players take control of a spaceship that flies over several different planets’ surfaces destroying the incoming enemy units.

The game contains two different game modes. “Mode A” keeps the games camera perspective in the same position. Players have control over their spaceships altitude while flying around the screen and can fire two different weapons. One weapon is meant for ground enemies while the other weapon is meant for aerial enemies. While the majority of the enemies are gun towers, ships and tanks that can be defeated in one shot, at the end of each round players will have to face off with a gigantic boss enemy that will require several shots to defeat.

Mode B is similar to Mode A, but now the camera follows the players ship’s movements instead. This mode also features a fixed target reticle in front of the player’s ship to help with aiming their fire.

Overview & History

Released exclusively in Japan in 1987 by ASCII Corporation for the Family Computer (Famicom), Geimos is an ambitious yet largely overlooked science-fiction action-strategy game. Dropping players into a futuristic cosmic conflict, the game challenges you to pilot a morphing spaceship across hostile alien landscapes and intricate planetary interiors. Unlike standard linear side-scrollers of its era, Geimos fuses fast-paced arcade shooting with resource management, requiring players to strategically deploy ground units and manage energy grids while fighting off swarms of extraterrestrial menaces.

Gameplay Features & Mechanics

The core gameplay loop alternates between top-down planetary bombardment and intense, enclosed grid-based exploration. Players control a versatile robotic vessel that can transform between an aerial flight mode and a ground-based mobile unit. The aerial mode allows for rapid transit across scrolling terrain and aerial bombing runs against alien infrastructure, while the ground mode lets players navigate tight corridors, collect vital power crystals, and engage enemy turrets directly. Combat relies heavily on upgrading your arsenal; players must collect energy pods to unlock stronger laser spreads and smart bombs capable of clearing the screen. Strategic depth is added via a map interface where you must coordinate defensive lines and protect your mothership from relentless alien incursions, making survival a test of both trigger finger and tactical foresight.
