Why Early Access?

“We've chosen to release OSO in Early Access to get feedback from our players about ways that the game can be improved upon.”

Approximately how long will this game be in Early Access?

“Likely less than a year. ”

How is the full version planned to differ from the Early Access version?

“The planned release will have Networking optimizations, lots more hazards, tons of maps, a map builder, and playtime rewards in the form of steam items, cosmetics, etc!”

What is the current state of the Early Access version?

“Currently we have a few different modes, players can customize their characters and join random players online. They can also play with friends.”

Will the game be priced differently during and after Early Access?

“The game will stay the same price!”

How are you planning on involving the Community in your development process?

“We will be updating the game and taking the Community's feedback into account as we add and adjust features. The look and feel of the game is important to us, and we want the Community to help us figure out where those things need to be improved. Discord will always be the primary way to give us feedback and speak with us directly during development!”

About This Game

OSO Is a 2.5D Platformer-Fighter that throws you and your friends into an Oscilloscope Inspired world where you fight to the death!

Fight! (With a Twist!)

  • Private and Public Steam Lobby System

  • 2-6 Player Online Multiplayer

  • Mutators for matches
