Exapunks
Exapunks is a programming puzzle game by Zachtronics where players write code to control virtual hacker entities called EXAs. The game features a narrative set in a retrofuturistic 1997, challenging players to hack, infiltrate, and manipulate systems across various puzzles. It includes a built-in code editor and a unique, physical-style manual for lore and clues.
Background
Zachtronics is a studio famous for hard puzzle games about programming and engineering (e.g., *Shenzhen I/O*, *Opus Magnum*). *Exapunks* (2018) is their take on hacking: players write tiny programs called "EXAs" to break into fictional computer systems in a retro-future world. The puzzles teach assembly-like logic and mimic real reverse-engineering tasks. It's notable for its in-game fictional operating system ("Murkwood"), a story set in a plague-ridden cyberpunk 1997, and for a built-in metapuzzle where players crack hidden passwords to unlock a secret ending. The game appeals to people interested in low-level programming, puzzle design, and Zachtronic's signature "open-ended" style — no single correct solution, just whatever works within harsh resource limits.
