"RoboGAL: Pluto Star Mission," a "Mega Man"-style mecha girl action game, is now available on Steam! A limited-time sale is also underway.

Publishers Nuntius Games and Vsoo Games have released the new action game *RoboGAL: Pluto Star Mission*, developed by Brazilian game studio TwinkleSoft, for PC (Steam).

The Adventures of a Cute Robot Girl

The game is set on Plutoベル, an island inhabited by biomachine lifeforms known as “GALs.”One day, a spaceship crashes on the once-peaceful island, throwing it into chaos. Ray Bo, a cheerful yet slightly clumsy GAL entrusted with managing the central tower that supplies the island’s power, sets out to explore the spaceship to determine the cause of the accident.

In the game, you’ll use jumps, slides, and shots to overcome challenging stages, and by defeating the boss awaiting you at the end, you’ll obtain a special weapon. The six stages can be played in any order you like, and the key to overcoming these threats lies in figuring out how to use your weapons effectively and identifying the weaknesses of the next boss.

While the visuals incorporate a classic 8-bit aesthetic, the game’s sound design and music are reportedly heavily influenced by titles such as *Mega Man 8*. Additionally, the music composed by Netoware appears to draw inspiration from Yosuke Yasui, ZUN, and the jazz-fusion band CASIOPEA.

Features of *RoboGAL: Pluto Star Mission*

  • Selectable Difficulty: Choose the gaming experience that suits you best from three modes: Chill, Classic, and Lunatic.

  • Free Stage Order: Explore unique, creative, and challenging stages in any order you like. Defeat bosses to obtain their special weapons.

  • Charming Characters: Cute and lively characters showcase their vibrant personalities every time you play.

  • Intuitive and Comfortable Controls: Customize settings to your liking, including auto-reload, continuous fire, and sliding controls.

  • Silliness at Full Throttle: Ray Bo is a bit of a klutz. There’s even a dedicated button just for “tripping”! Be sure to find out for yourself what it’s for!
