An open-ended programming game in which you optimise 4-core assembly code to maintain a 1990s alt-history dystopian megacity's infrastructure. Take jobs from middlemen with hidden agendas and uncover the chilling consequences of your "routine" fixes in this assembly language puzzle thriller.
Navigate the complex infrastructure of a 1990s alt-history megacity as you take on mysterious jobs in this simulation game. Each fix could have chilling consequences, unraveling the truth behind your routine tasks.
About this game
The city runs on LANE-4 - a quad-core microcontroller embedded in everything from train switches to power grids. The infrastructure is failing. You've been hired to help keep it running.
Write microcode in a custom assembly language. One program runs across all four cores simultaneously - the same instructions, different data. When cores collide on shared memory, the chip resolves it: two writers take the minimum, three take the maximum, four take the sum.

Take contracts through email chains from fixers, corporate middlemen, and bureaucrats.
Every job looks routine. Whether it stays that way is another matter.

What you can expect in the full version:
50+ puzzles across 5 acts
Write assembly for a quad-core SPMD processor - one program, four cores, shared memory
Unique collision mechanics resolve simultaneous writes through min, max, and sum operations
Optimise solutions for Cycles, Area, and Instruction Count
Histograms to compare your solution against others
A narrative told through email chains from various characters
Set in an alternate-history Australian Megacity in 1996 - where Soviet influence shapes the world
