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