A co-located mixed reality VE-Sport experience. 2 to 20 players at once. One physical floor. Real bodies, growing trails of Minions — in an arena that scales to fit the room.

Sport, reborn as a spatial scramble.

Goo Goo Clash collapses the line between sport and game. You don't sit. You don't tap. You move — for real — and the system answers in mixed reality.

Co-located /01

One floor. Up to twenty players. No hiding.

Players share the same physical floor — a real arena that scales to the room. Same room, same air, same gravity — only the slimes and Minion trails are digital.

Mixed Reality /02

Real space. Digital slimes.

MR passthrough lets you see your opponents' real bodies and real eyes — overlaid with the food, Minions, and trails you'll have to read in motion.

VE-Sport /03

Made to be played, not watched.

Virtual Environment Sport. You'll feel it in your legs the next morning. The arena rewards reflex, positioning, and footwork.

Broadcast /04

The match as a stage.

An external MR camera turns each match into a watchable broadcast — a clean external POV that makes the digital layer legible to crowds.

Three rules. That's the whole game.

/01

Move, eat, grow.

Run on the real floor. Eat food to spawn Minions that trail behind you. The longer your chain, the more space you control.

/02

Stop for three seconds — you die.

The arena punishes hesitation. There is no standing still, no safe corner. Keep moving, or get reset.

/03

Wear the crown.

Whoever leads the score wears a crown floating above their slime — visible to every player and every spectator, all match long.

02 / 07

Peer reviewed. Conditionally accepted.

Five SIGGRAPH 2026 reviewers and the Immersive Pavilion committee weighed in. Verbatim pull quotes from the official review pass.

COMMITTEE

"The committee was very impressed with the overall polish of the submission. From the video it looks very fun to play. It also does a good job of showing off what is possible with multiplayer AR experiences. Overall we felt this was a very solid submission."

SIGGRAPH 2026 Immersive Pavilion Committee
REVIEWER 01

"Untethered Mixed Reality multiplayer games aren't something you see often. The game looks really fun to play from the video. Having a simultaneous spectator view is a nice touch so the people watching can see what's going on as well."

REVIEWER 02

"This feels like a solid and practical system that is already close to a deployable consumer experience. It seems well suited for events, public installations, or entertainment venues."

REVIEWER 03

"Your approach to mitigating the isolating tendencies of traditional VR is perceptive, and I appreciate how the project leverages mixed reality to promote social interactions."

REVIEWER 04

"Goo Goo Clash takes it to the next level by implementing a multiplayer MR experience with competitive gamified elements. I believe many attendees would like to play this game with their peers."

REVIEWER 05

"A significant strength of the project is its accessibility — the system does not rely on handheld controllers or external physical base stations for tracking, leveraging standalone hardware instead."

03 / 07

A floor that scales to the space.

The arena is size-agnostic. One admin headset scans the room, drops a shared anchor, and players step in — and it scales with the space — from a tight two-player duel to a twenty-player free-for-all. The only real limit is networking. At SIGGRAPH it stages in under a day within the pavilion footprint.

Drape Boundary

Soft drape fence frames safe play. Visible to spectators, friendly to falls.

Powered by Meta Quest 3.

Five headsets share one spatial anchor so every player sees the arena in exactly the same physical spot. Mixed reality passthrough keeps the real world visible — digital food, scoreboards, and opponents overlay the room.
