About This Demo

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!)

Have you ever played a fighting game with your friends and thought "Well this is fun, but it could be more chaotic"?

Welcome to OSO, where you get to add hazards to the map whenever you die! Throw down a fan and launch your friends into the void, or kick them into a well-placed spike to get your revenge.

Play with Friends and Foes Alike

OSO supports matches of up to 6 players, so grab some friends and hop into a private lobby! Don't have anyone that's willing to get thrown into a spike wheel? That's ok too! With public lobbies, you can find some like-minded players and punch the pixels out of each other.

Demo?

The Demo has all the features the full game will have, except for the Custom Mutators for matches. Currently you can only  change your player count or if your lobby is Private or Public. As well as we will also be optimizing our Netcode to make the game play feel more responsive in the future. (Demo will also be updated)

Features:

  • Private and Public Steam Lobby System

  • 2-6 Player Online Multiplayer

  • Mutators for matches! (Demo only includes player count slider. Full Version will have MUCH more)

  • Dashing, Hazards, and crazy Combos to destroy your friends!

  • Customize your character with our many Oscilloscope Inspired Colors!
