The greatest collection of fighters in the universe... weren't available.

Bash, blast and chomp your way to victory in this tournament of creatures, weirdos and not-quite-heroes. 

The Grand Slamboree is a 2D Platform-Fighter, where every hit is lethal for intense, fast-paced rounds. With simplified movesets, anyone can join in the brawl, while leaving plenty for dedicated players to master! Play locally with up to 4 players, use the Steam Remote Play Together feature to brawl online with friends, or fill out the party with bots to maximise the chaos!

Play as 6 different fighters, each with their own unique playstyle! Give them a good thump as Donk Jinglebash, blow them to smithereens as Bombshell, or reel them in and swallow them whole as Sporgi.

Play on 120+ stages across 6 worlds, with their own interactables and hazards! Avoid angering Refbot at The Mechanasium, capture the altars at King's Castle or collect gold to spend on items and assists in the town of Dingleford.

Set your own rules! Score as many points as possible in 'Slam Rush', or survive to the end in 'Last One Standing'. Play individually or in teams. Set everything from map selection, hazards, point limits and round times. It's up to you!

Please note that the game does not come with full online multiplayer at launch, but it is being actively worked on.
