Games Like SIGNOS: AI Robot Builder
Build the robot. Design the tactics with Thought Tiles. Then just watch. Assemble the 18cm-tall autonomous hobby robot “SIGNOS” and program its behavior logic with flowchart-style “Thought Tiles.” No controls during battle — SIGNOS fights on its own, guided solely by the logic you designed.

SteamAbout SIGNOS: AI Robot Builder
No piloting skills required.
Build a robot.
Work out how it should fight.
Then hand it over to the AI.
“SIGNOS” is a fully automatic battle simulation in which the robots you design fight each other.
The player never takes control during a battle.
Should it move?
Should it search for the enemy?
Should it attack?
How should it judge the situation?
It all comes down to the logic you built.
How will the tactics you imagined actually play out on a real battlefield?
Seeing that through — that is what a SIGNOS battle is.
Build Your Machine
Combine all kinds of parts on the 18cm-tall hobby robot “SIGNOS” to create a machine that is yours alone.
Head, chest, arm and leg parts each have their own performance.
Durability, weight, EN consumption, processing power, firing arc.
A heavy build loaded with high-firepower weapons.
A machine that leans on its shield to grind out a win.
A machine that prioritizes mobility to control the distance to its opponent.
The parts you choose change the way your machine fights.
And then — what logic will you build into it?
Combine machine design with tactical design and complete a SIGNOS that is entirely your own.
Build Tactics with Thought Tiles
Place Thought Tiles such as “Move,” “Search,” “Attack” and “Judge,” then connect the nodes to build your behavior logic.
For example:
Search for the enemy
↓
Judge the distance to the enemy
↓
Choose whether to attack or move
Piece by piece, you assemble behavior that responds to the situation.
Start with simple logic, then add more conditional branches.
“How do I want it to act in this situation?”
One at a time, you turn the tactics in your head into logic.
How Smart Can You Make It on Limited Memory?
A SIGNOS head comes with a limited memory capacity.
Build in more complex decisions and it can handle more situations.
But cram in too much logic and it overloads, delaying execution.
And that is exactly why:
it is not only about what you build in — what you cut out matters just as much.
Pick only the processes you need within a limited memory, trim away the waste, and distill your tactics into a single piece of logic.
Building a strong machine alone will not win you the match.
What kind of mind will you give it?
That is what decides victory and defeat.
Battles Are Fully Automatic
Once your logic is finished, the battle begins at last.
From there, all you do is watch.
SIGNOS acts on its own, following the logic you built.
It finds the enemy exactly as you intended.
It moves to the range you were aiming for.
It attacks at just the right moment.
When the tactics you designed click into place, your machine seizes victory on its own.
But things do not always go the way you planned.
“Why didn’t it attack right there?”
“Why did it close in at that range?”
“Was this the condition I was missing?”
Look at the battle results, revise your logic, and send it out again.
Design → Battle → Analyze → Improve
That cycle of trial and error is exactly what makes SIGNOS fun.
Story Mode
Take on a series of rivals together with Rei, the protagonist, and Hal, the mechanic.
Story Mode runs for 5 chapters plus an epilogue.
As the story unfolds, it is designed to teach you step by step, from the basics of AI building to advanced branching logic.
Logic that started out simple evolves into complex tactics with every battle you fight.
Along with the story, sharpen your own power to build logic.
Fight Logickers from Around the World
Once the story has taught you the basics, head into asynchronous Ranking Battles.
Face off against the SIGNOS units players around the world have built.
What tactics has your opponent’s AI been loaded with?
Will your logic hold up against other players?
Earn new parts as victory rewards and strengthen your machine and its logic even further.
Learn other players’ tactics, refine your own, and challenge them again.
Put your logic to the test against the world.
How Would You Make It Fight?
Run rings around them with speed?
Push straight through with firepower?
Read their movements and meet them head-on?
Within limited parts and limited memory, find the answer that is yours alone.
You do not pilot. You design.
Entrust the tactics you devised to your robot.
That is SIGNOS: AI Robot Builder.
