Xexyz (pronounced zeks'-zees/zeks'-iz), known in Japan as , is a 1988 video game published by Hudson Soft for the Nintendo Entertainment System. The game was released in Japan on August 26, 1988, and saw a North American release sometime in April 1990. The game was never released in Europe and the game is not playable on PAL consoles. The story takes place in the post-apocalyptic year of 2777, after Earth has been devastated by nuclear war and natural disasters, with the island nation of Xexyz now being threatened by alien robots. The Japanese Famicom version is based on the tales of Urashima Tarō, features cutscenes throughout the game, a choice of three endings and has minor graphical differences in some of the NPCs. Gameplay The game revolves around the main character Apollo, who progresses through the game in an alternating format that switches between platform, side-scrolling action (similar to the Super Mario Bros. series) and side-scrolling shooter action (similar to Konami's Gradius series). The goal of the game is to destroy the evil Goruza, rescue Princess Maria, and save the planet. In the platforming levels, defeated enemies drop life ('L' blocks) or money ('E' blocks) power-ups. Apollo can collect the currency of the land ('Balls'/'E Ball') in order to exchange it for power-ups and information, as well as access to minigames. Vendors are scattered throughout the platforming levels through doors or hidden gates. In the shooter levels, the player can obtain 'S' and 'P' items that upgrade speed and weapons, respectively. Platformer gameplay The odd-numbered stages in the game (1, 3, 5, etc.) utilize mostly platform-style gameplay. These stages work in the familiar manner; the character progresses at his/her own pace, picking up new weapons and power-ups along the way. To leave the initial area of each of these levels the player has to collect a "force star" by defeating an enemy found in a hidden room. Once this star is obtained the character is able to enter the "mechanical castle" in the region. The mechanical castles, being mazelike indoor environments full of robots and machines, stand in stark contrast to the earlier parts of each level, which are organic outdoor environments. Each mechanical castle also has a brief auto-scrolling shooter segment through which the player must pass; these segments foreshadow the imminent transition to the following even-numbered stages. The segments in question consist of a sequence of corridors, at
