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!

MUMO Studio announced that Dubium will launch to Steam Early Access on June 14, 2023 for $14.99.

With a space-station setting and gorgeous graphics, the Early Access release will include a brand new playable character, fresh character cosmetics, an enhanced Battle Pass, a lobby chatting system, and tons of updates based on player feedback. The sci-fi co-op title will be available for $14.99 USD for players who can’t wait to experience the sense of desolation in space and the tension and excitement of winning by a narrow escape.  

“After three successful playtest events, we’re indebted to the thousands of players who took the time to share their thoughts on our project. We’re incredibly proud of all the features and enhancements our development team has implemented over the last year, and we can’t wait to introduce Dubium to a broader audience. We’ll continue working very closely with the community as we update the game on the road to its 1.0 launch,” said KiHoon Choi, CEO and Game Director at MUMO Studio.

Dubium’s Early Access release includes plenty of new features for those gutsy enough to launch into outer space with treacherous fellow mercenaries. At launch, players will have the chance to unlock new cosmetics for characters, accessories, and gadgets, plus handy customizations for specialized character gear. To improve the experience for new players, MUMO Studio refined the player tutorial, alongside general enhancements such as updates to inventory management, AI responses, matchmaking, daily missions, loot, and more. 

MUMO Studio will also add a new playable character to the game’s roster of Frontiers. An ex-hunter with an expert knowledge of traps (not to mention a clinical case of germophobia and OCD), Archie Lang joins DUBIUM’s crew at Early Access alongside its core members: Sobok Ee the ambitious diver, Jessica Fernandez the ex-soldier, Ryan Goldman the white collar psychopath, Zack Zhou the infamous hacker, and Sergei Tulinov the capricious former wrestler.

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 2023.
