Hex Reverse Launches Free On Steam For First 30 Days
A solo developer shipping a full roguelike deckbuilder while openly listing which parts of the work were handed to AI, and then giving the game away for a month, is a distribution and disclosure pattern worth watching as AI-assisted solo releases become more visible on Steam.

Individual developer IsaoWorks released Hex Reverse for PC on Steam on October 7. The game is free for its first 30 days, after which it is planned to sell for 300 yen; players who add it to their library now keep it playable after it becomes paid. It combines a hexagonal territory-capture card battle with roguelike deckbuilding, and its Steam page discloses the use of generative AI tools including ChatGPT, Codex, SOUNDRAW, and ElevenLabs for planning, code, some graphics, and audio.
Hex Reverse is a territory-capture card battle played on a 19-tile hexagonal field. Players and the opponent alternate placing cards, each with different numbers on its six sides, and a higher number on a touching edge flips the opponent's card to your color. Wins let you take one card from the opponent's deck, and skills, attributes, special rules, and special fields change the conditions between runs. Between runs you return to a base for deckbuilding, card buying and selling and combining, and permanent equipment upgrades.
The Steam store page discloses generative AI use. ChatGPT handled planning, specification organization, reviews, and some graphic assets, while Codex handled code generation, implementation, and testing support. Some images are AI-generated bases adjusted in Photoshop, SOUNDRAW produced some BGM, and ElevenLabs produced some sound effects. No feature uses generative AI in real time during play, and final design, editing, implementation, and adoption decisions remain with the developer.
