Rebranded as RS34, the developers opened "The Clean Rooms Project" on the Campfire crowdfunding platform in 2024, leading to remastered ports for Nintendo Switch and PlayStation consoles in Japan. Karous for Windows through Steam will launch on Thursday with added English-language interface and subtitles.
A central gameplay mechanic encourages the player to consider how every attack makes you stronger. The Steam product page reads, "Your main options are Shot, Sword, and Shield. The more you use them, the more powerful they become. Mix and match your weaponry as you tackle each stage."
Original music is by Ko Hayashi and Daisuke Nagata, credited under the collaborative alias k.h.d.n. The Karous Soundtrack Original & Remixed teaser movie can be viewed on the developer's YouTube channel.
From the product page:
Slash, shoot, guard, grow! Karous, a Dreamcast shoot 'em up originally released back in 2007, is now soaring onto PC. Play as Karous, a girl who lost her parents in a great war with humans. Driven by her father's dying words, she descends to Earth in search of the Sanguis Dei.Steam - Karous
