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 is excited to welcome players to the first closed beta test for Dubium, but players will need to wait a little bit longer!

In preparation for opening the servers to the public, pre-beta testing surfaced some problems with servers and matchmaking that would cause issues for players wanting to participate in the beta. The developers have decided to take a couple of extra days to iron out the wrinkles before starting the beta in an effort to provide players with the best experience possible and they appreciate your patience!

The closed beta is now planned to be available between December 17th and 23rd.

"While we were doing a final polish of the beta build, we found a critical server issue that can affect the core gameplay of Dubium. The developers have tried fixing this issue in time for the original beta start date of December 15th, but as the deadline approached we realized that it would require more time to fix the issues for the best beta gameplay experience. Unfortunately, this means we have made the difficult decision to delay the beta test by a couple of days."

"We are very sorry for the inconvenience. It is quite frustrating for an indie developer like us to deliver this sad news but please hang in there and wait just a little bit longer! We're confident you'll enjoy what Dubium has to offer. Thank you for your understanding and patience while we work hard to bring you a better version of DUBIUM so that you can enjoy the experience as intended."

In the meantime, everyone interested in checking it out can sign up on the official DUBIUM website for a chance to be included. If chosen, players will receive an email with instructions and a beta test key to redeem on Steam. Registration will remain open throughout the test period. There will be no restrictions on showing off gameplay during this event and both media and content creators are strongly encouraged to showcase Dubium on their channels and outlets!
