A physics-based multiplayer party brawler. Hurl Rock, Paper, and Scissors at friends or bots that clash mid-air, shatter arena platforms, and pile up as obstacles. Grab powerups that bring endless chaos to each round. Brawl with up to 8 players online or on LAN.

Ro Sham Brawl is a multiplayer party brawler where you throw Rock, Paper, and Scissors objects at opposing players. Every shot is a physics object — it flies, bounces, and never leaves the arena. The map fills up, platforms crumble, and every round spirals into something different.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/4804af4a1d3040040888539da884ff86.poster.avif?t=1776194917" width=800 height=450 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/4804af4a1d3040040888539da884ff86.webm?t=1776194917" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/4804af4a1d3040040888539da884ff86.mp4?t=1776194917" type="video/mp4"></video>Rock crushes Scissors. Scissors cuts Paper. Paper covers Rock. The winning object destroys the other object and becomes a persistent threat on the arena. The same rules apply to the arena itself: platforms are made of Rock, Cardboard, or Plastic, and the right projectile type smashes right through them.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/c00ae58706f6924abfd126f6113f52fd.poster.avif?t=1776194917" width=800 height=450 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/c00ae58706f6924abfd126f6113f52fd.webm?t=1776194917" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/c00ae58706f6924abfd126f6113f52fd.mp4?t=1776194917" type="video/mp4"></video>Powerups That Stack. Pickups spawn across the arena and modify your projectiles directly. Homing rocks that chase opponents. Ricocheting scissors that bounce off every surface. High speed paper that is impossible to dodge. Shotgun spreads, explosive impacts, gravity wells — and they all stack on top of each other. The longer the round goes, the wilder things get.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/1bc829d211d7d8d176035de956b668f7.poster.avif?t=1776194917" width=800 height=450 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/1bc829d211d7d8d176035de956b668f7.webm?t=1776194917" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/1bc829d211d7d8d176035de956b668f7.mp4?t=1776194917" type="video/mp4"></video>Arenas That Don't Survive. Breakable platforms shatter when hit by the right projectile type. And since projectiles never despawn, they pile up as rolling, bouncing obstacles. The arena you start on is not the arena you finish on.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/f1fcd17b6976dd397f95bbbe25c471ba.poster.avif?t=1776194917" width=800 height=450 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/f1fcd17b6976dd397f95bbbe25c471ba.webm?t=1776194917" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4578640/extras/f1fcd17b6976dd397f95bbbe25c471ba.mp4?t=1776194917" type="video/mp4"></video>Bring Friends.
