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.
LANE-4: A Dystopian Programming Thriller
SteamThe 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.
