Ranger X

The player assumes the role of Ranger X, piloting a powered exoskeleton who leads the fight back for his home planet against the invading Rahuna forces. Ranger X is equipped with a jet pack and an assortment of weapons. The jet pack allows for short periods of flight, the duration of which is limited by the jet pack's temperature. Upon overheating, the player must land and wait for cool down.

Alongside Ranger X's standard pulse rifle, the player has access to various special weapons including a flamethrower and homing attacks. Unlike the pulse rifle, the special weapons drain a power bar, which can only be recharged when Ranger X is in a bright light source. This special arsenal can be increased by collecting power ups scattered across the levels. On certain levels, the player may also control a supporting vehicle – an Ex-Up, such as Indra – a futuristic motorcycle, a premise described as "RoboCop on a Harley".

Ranger X was first project to be developed by GAU Entertainment (now Nex Entertainment), a Japanese video game developer founded by former Wolf Team staff, with both Toshio Toyota and Toshio Yamamoto serving as designers, with artist Ree Senfhu co-creating the pixel art, in addition of Yoshinobu Hiraiwa acting as composer and Noriyuki Iwadare creating the sound effects. The team recounted the project's development process and history through various Japanese publications.

Yamamoto claimed that the team created Ranger X with a lot of intuition without copying other titles, not wanting to be bounded with the need to imitate others, as their goal was to make a Sega Mega Drive game of high-quality. However, Yamamoto commented that the team did not think about the graphics but due to the emphasis on creating a polished game, the visuals ultimately had "a lot of shine too". Yamamoto remarked that the team did not use game design documents, as the team added elements on the fly when memory space was available. Both Toyota and Yamamoto wanted the animations to feel intricate, as robots have more possibilities and the team worked to make as much animations as possible for sprites.

Critical reception was generally positive. Mega praised the tactical opportunities offered by the different weaponry, and the need to manage the supporting vehicle. Similar sentiments were echoed in Sega Force Mega and GamePro, who felt that "the unique dual action of flying and riding a motorcycle gives this game a step up against over other shooters".

The graphics impressed, with some reviews claiming that Ranger X had broken through the Mega Drive hardware's color limitations. Almost every aspect of the graphics were praised, from the detail of the backgrounds, to the clarity of the sprites, and even the presentation of the cutscenes. EGM felt that Ranger X featured "some of the best graphics ever seen on the [Mega Drive]". MegaTech however, noticed that the game exhibited "a bit of sprite flicker when things get busy".
