If you love sports and fast-paced action, Sparkball will be one you need to check out with a playable demo coming in Steam Next Fest.
What is it? Sparkball pits two teams of four in fast-paced, high-stakes matches where players brawl, block, and score in a futuristic arena. Matches are short, intense, and highly replayable, making the game easy to pick up but tough to master. The game celebrates versatility, rewarding both "ballin' and brawlin'", with the top players effortlessly blending them as each unique situation demands. Whether blocking shots, setting up plays, scoring goals, or simply out-duelling your opponent, there’s something to love for every type of gamer.
For the demo and release, I've been told there will be "no anti-cheat at this stage (regardless of platform)" and their focus is on Steam Deck support for it too. So looks like potentially another fun multiplayer title we can play with Valve's Proton on Linux systems.

Created by Opti Games which has developers who previously worked on the likes of League of Legends, World of Warcraft, Overwatch and more. From the rather brief actual gameplay in the trailer, it looks very chaotic. Exactly my kind of thing.
