About This Game

Colony Sim. Assembly Required. Every robot in your colony is driven by a cycle-accurate MOS 65C02 microprocessor, the legendary 8-bit chip that powered the Apple II, Commodore 64, and NES.

Every robot ships with a working 65C02 operating system and starter routines so you can command your colony and tweak existing code right away. When you are ready to pop the hood, there are zero guardrails: you get full access to 64KB of RAM, memory-mapped I/O ports, and the raw _os.s and _irq.s source files to optimize every cycle or build your own robot OS from scratch.

Step through your code line-by-line with the live visual debugger, look up opcodes and I/O ports in the built-in C64-style Programmer's Reference Guide, or write code in the in-game editor or your favorite external editor with instant hot-reload. Every routine you assemble packages onto a versioned Boot Disk and adds clickable buttons to your HUD, so you can fix a bug once and selectively flash the upgrade to individual robots or squads in the field.

On an alien frontier, software efficiency is physical survival. Every instruction, sensor ping, and wheel turn draws real power from your battery cell. Wasted movements and spinning loops leave robots powered down in the dirt, while tight code and low-power sleep states save enough juice to harvest resources and build your perimeter walls.

Navigate corrosive ionic shallows and automate Silicon perimeter walls before sunset, when predatory Electrocrabs emerge from the dark to drain your robots dry. Reinvest harvested Silicon and volatile purple Curium into a 5-tier tech tree to unlock faster CPUs, expanded RAM, ultrasonic sensors, and heavy drills.
