Welcome to Splatterbox! ...a living ecosystem of colorful blobs, terrible decisions, and consequences that refuse to stay contained.
Your world is built from millions of fully simulated cells. Liquids flow. Heat spreads. Structures collapse. Materials react with everything around them.
This would be manageable.
If it weren't for the blobs.
They dig, carry, build, and cooperate like an enthusiastic team of very under-qualified helpers. Give them a task and they'll try their best ... often by walking through fire, collapsing the ground beneath their feet, or triggering a chain reaction you now have to deal with.
Think less workers. More toddlers with access to the controls of reality.
You're here to take care of them.
Guide, don't command
You don't control your blobs directly. They think for themselves, act on their own, and make mistakes faster than you can fix them. You shape the world around them, assign tasks, redirect flows, reinforce terrain, build safeguards... and hope it holds.
A misplaced dig can drain a lake.
A spilled liquid can flood a valley.
One bad decision can become everyone's problem.
When blobs splat — and they will splat
Each blob is made of vibrant, reactive gel. When they splat, they leave behind bright, colorful gel that becomes part of the simulation. It flows. It blocks. It fuels. It reacts.
Need to plug a leak? Stabilize a structure? Feed a system? Sometimes the most efficient answer is a well-placed splat.
Sometimes you'll save them.
Sometimes you'll contain the damage.
And sometimes the cleanest solution is to accept a small loss before it becomes a very large, very liquid one.
Cleaning up the aftermath is part of the job. So is deciding when not to.
A simulation that doesn't fake anything
Splatterbox is powered by a custom GPU-driven engine running millions of cell updates per second. Inspired by "falling sand" games and cellular automata. The entire world is fully destructible and continuously simulated — no fixed outcomes, no scripted disasters. Complex behavior emerges from simple rules colliding at scale.
Every world evolves differently. Every catastrophe is uniquely yours.
Solo or co-op
Play alone, or team up in co-op multiplayer to coordinate, improvise, and watch everything spiral out of control together. It won't make things easier.
But it might make them survivable.
(Or at least more entertaining when it isn't.)
