The inZOI team has published another revision to its ModKit roadmap — and this one carries the biggest change yet: script mods are being rebuilt around Lua instead of Blueprint, and won't arrive in 2025 at all.
A single-issue hotfix on August 25, 2025, build 20250825.6945.W for Windows PC (Steam).
Two days after launch, August 22, 2025 brought a broader hotfix — most of it aimed at City Trips, the new travel system that has become the update's biggest source of problems.
The August update is comfortably the largest inZOI has had. Alongside the free inZOI: Island Getaway DLC, v0.3.0 brings the game to Mac, lets Zois travel between cities, and adds swimming, fishing, farming, mining, loans, insurance and 14 vehicles. It went live on August 20, 2025.
Two weeks after the ModKit's launch, the inZOI team has revised the rest of its 2025 modding roadmap — with a delay and a cancellation.
Version 20250620.4836.W was applied on June 20, 2025, with a mix of relationship, stability, and modding fixes following the June update.
The long-awaited June update has arrived. Version 20250612.4545.W went live on June 13, 2025, bringing the ModKit, over 200 new items, and a substantial rework of how Zois form families and relationships.
The inZOI team has published its answers to the ModKit AMA, working through community questions days before the toolkit ships. Several answers go well beyond what previous announcements covered — particularly on monetisation, scripting, and what the June release won't do.
The delayed May update now has a firm date: Friday, June 13, 2025. Lead developer Kjun opened with another apology to players who waited, then laid out a substantial feature list — the ModKit, roadmap items from the showcase, and a significant reworking of how families and relationships work.
With the ModKit now due in mid-June, the inZOI team is collecting community questions about modding in a dedicated AMA — and has opted for a written format rather than a live session, saying it wants the answers to be accurate and detailed.
Lead developer Kjun has published a new letter with two headline items: the update originally planned for the end of May — modding system included — has slipped to mid-June, and the team wants to correct some misconceptions about what the ModKit actually is.
The May update described below was delayed to mid-June 2025, taking the initial modding features with it.
Kjun, the lead developer for inZOI, has just released another insightful letter, offering a glimpse into the team's current development efforts and the future trajectory for the game. The letter addresses player feedback on recent hotfixes and outlines exciting plans for the May and August updates, as well as longer-term goals.
The ModKit launch has been postponed to mid-June 2025 along with the rest of the May update. See Kjun's letter on the schedule change for the details, including confirmation that scripting won't be in the initial release.
Big news from the inZOI team: the highly anticipated inZOI ModKit is scheduled to launch in late May 2025, and it's bringing a wave of official tools to empower your creativity! Alongside this, Krafton has shared a detailed modding update roadmap stretching throughout 2025.
