Dubium is a 5-player social deduction game set in a near-future sci-fi universe.

Players take on the role of Frontier or Traitor and must escape from an abandoned space station by any means necessary. Frontiers will cooperate to repair solar panels that power the escape pod while trying to uncover the identity of the sole Traitor.

Players must not relax until they escape; the Traitor will sabotage the Frontiers’ efforts at every step as they try to complete their own mission. The Traitor needs to hide their identity and use deceit and treachery to take the Frontiers out one by one in order to escape the station unopposed.

Everyone wants to get out alive. Trust no one!

Today MUMO Studio launched the final public beta test for Dubium.

Feedback from the community and continued development has led to compelling additions like a comprehensive in-game tutorial, a gadget workshop, and a character growth system with daily missions and rewards. The final test is a significant improvement over the successful Steam Next Fest test in October 2022 and gives players a clearer sample of what they can expect when Dubium launches into Steam Early Access later this year.

Dive into Dubium— no keys required!

The open beta is available now on the DUBIUM Steam page, for anyone brave enough to take the plunge into outer space (alongside some suspicious fellow Frontiers). Players can explore MUMO Studio’s game of fun and treachery from March 27th to April 10th, 2023. Those interested in Dubium lore can get further immersed in the sci-fi world by watching the above prologue trailer.

“We’re proud to present the latest upgrades to Dubium, following the amazing community engagement we saw last fall. Dubium is an evolution of the social deduction genre that we hope delivers an immersive and satisfying gameplay experience.” says KiHoon Choi, CEO and Game Director at MUMO Studio. “Since Dubium’s space station includes many ways to interact, scheme, and survive, we heard from players that we needed to implement a robust tutorial with updated guide videos. Dubium may seem simple on its surface but players have been surprised by the depth it has to offer. We want to welcome new players with open arms, showing them all they can do as Frontiers and Traitors, while also offering a deeper understanding of the unique tools each character can access.”

Key Features:

• Survive In Space - An explosion from an undisclosed experiment has damaged the space station and it is now a restricted area filled with danger. You must restore life support systems, collect oxygen canisters to breathe, repair solar power generators as quickly as possible, and escape before the space station explodes.
• You are a Frontier - Your mission is to search the space station and retrieve all the Cores left over from the explosion. During your expedition, you’ll come across valuable Keystones. Don’t forget to collect them, as they have great value and can make you rich! 
• You are a Traitor - As a Traitor, you secretly work for the nefarious competitor company, Blamane, on a mission to collect 10 Keystones and escape before the Frontiers notice you aren’t on their side. The other players are nothing more than mere tools for the success of your mission. Act like an innocent Frontier to gain their trust, then approach them at the right moment to take them down and steal their precious Keystones. Be stealthy or bold – the choice is yours.
• Escape from the Space Station - Dying means you get to keep nothing. You must come out alive with Keystones to become rich. In the best-case scenario, you may collaborate on the mission and escape as a team. However, a solo escape is always an option when things are looking grim… Your own survival is the top priority after all.
• Trust No One - One of you is bound to be the Traitor. Even after the Traitor dies, there’s always a chance of a fellow Frontier being bought over by Blamane and becoming the new Traitor. Watch your back and trust no one.

Dubium is coming to PC (Steam) in Q2 2023.
