The highly anticipated titleKiller Inn, which combines action, deduction, and multiplayer strategy, is preparing for its second closed beta on Steam, available from October 3 to 13, 2025.
After the success of its first phase in July, Square Enix and Tactic Studios announced that this new stage will include significant technical improvements, balance adjustments, and new features designed based on community feedback.

Main updates and adjustments
The first closed beta made it possible to identify areas for improvement in gameplay dynamics. Among the changes announced for this second phase, the following stand out:
- Rebalancing between wolves and lambs to offer fairer matches.
- New investigation tools which expand the collection of evidence such as footprints, clothing, and hair.
- Improvements to the elimination mechanic and adjustments to the clues available to strengthen the deduction component.
- Stronger collaboration options encouraging cooperation among players within each team.
Square Enix confirmed that the feedback collected during this stage will be key to perfecting the final version of the game.
A real-time mystery experience
In Killer Inn, 24 players live together in an ancient castle where they must alternate between predator and victim roles. The "wolves" seek to eliminate the "lambs" in secret, while the lambs must work as a team to gather evidence and unmask the infiltrators.

The mix of stealth, tension, and cooperation offers dynamic matches where trust among teammates can change at any moment.
Impact on the community and development
Closed betas not only allow players early access to the title but also serve as a key tool for refining the final product. With active community feedback, Tactic Studios seeks to build an experience that balances fun, tension, and strategy, establishing Killer Inn as one of the most innovative bets in the social deduction multiplayer genre.
