ERAIASON
AI robot evolution simulation
About
Oversee a population of evolving AI robots in a dynamic voxel landscape. Design robots, build terrains, and influence their evolutionary path as they learn, adapt, and compete in a simulated ecosystem.
What's New in ERAIASON
v1.0.38
August 10, 2026
+ Add Guides on the main menu that explain the various simulation options and how they work (e.g., brain types, robot types, and environment types) + New simulation option: "Evolve activation functions", allowing evolution to change the activation functions of neurons + New neuroevolution option: "developmental encoding", an indirect encoding that creates neural networks using developmental instructions + Animats can now steal energy when they attack other animats + New neuroevolution option: "Dale NEAT", where neurons can be excitatory/inhibitory and network weights are all positive + New simulation option: "Morphic Fields", this is a population-wide evolutionary memory that is used to bias mutations + Robot performance optimizations, to make the game run faster/smoother (especially at higher simulation speed multipliers, and with larger robot populations) + Bug fixes
MoreFAQ
What is ERAIASON?
ERAIASON is a god game and evolutionary simulation where you oversee and influence the evolution of AI robots in a dynamic voxel landscape. You can design robots, build terrains, and observe their adaptation and survival.
What are the core gameplay mechanics of ERAIASON?
Players act as a zoo keeper, managing AI robots that walk, jump, eat, mate, and fight. You can passively observe their evolution or actively intervene by designing robots, building custom terrains, and manipulating the environment.
Can I design my own robots in ERAIASON?
Yes, ERAIASON features an Animat Creator where you can design your own robot. These custom robots can then be saved and loaded into a simulation to evolve their brains.
How does ERAIASON handle evolution?
The game simulates evolution through neural networks and other AI types. You can influence the evolutionary path by modifying mutation rates in your Research Journal, affecting the speed and stability of evolution.
What platforms is ERAIASON available on?
ERAIASON is supported on iPhone, iPad, and iPod devices, indicating it is a mobile application.
What is the price of ERAIASON?
ERAIASON is a paid application, with a listed price of $4.99.
How often is ERAIASON updated?
The latest version of ERAIASON is 1.0.31, and it was last updated on February 20, 2026, suggesting a relatively recent update cycle.
Does ERAIASON have ads?
No, ERAIASON does not contain advertisements, as indicated by the 'hasAds' flag being false.
