4th Branch Opens Steam Page for Block Sim blockia, Fall 2026 Release Planned
The store page opening formalizes a two-person project that had only been tracked through koeda's development posts on X, putting a concrete fall 2026 date on the team's first joint release.
Reporting from 1 source: Game Spark.
4th Branch has opened the Steam store page for blockia, a block simulator built around free creation with no set goal. The game offers more than 120 part types, spanning basic blocks, buildings, furniture, nature, and decorations. A recipe feature lets players assemble example builds such as Rocket, Rabbit, or House piece by piece. Completed works can be photographed in Photo Mode, kept in an in-game album, and exported as images. The PC (Steam) release is scheduled for fall 2026.
The announcement came through the store page rather than a dedicated stream, following koeda's development updates on X. 4th Branch is a two-person team: koeda, who developed the deck-building roguelike ANTHEM#9, and indie creator 4423. blockia is the pair's first work together. Creation runs on simple controls: pick a part, place it, then change its color and orientation. Recipes cover the cases where a blank canvas stalls the player, with guides for part shapes, colors, and placement. Finished builds can still be rearranged afterward, and photographs can be taken in Photo Mode with adjustments to composition, background, lighting, and color tone.
