Developer recreates classic shoot ’em up Zaxxon as a UEFI firmware — isometric arcade game coded in x86 assembly for no-OS represents ‘total freedom from big tech’

Inkbox Software has released a recreation of a beloved isometric arcade game that runs directly from a PC’s Unified Extensible Firmware Interface (UEFI). Moreover, they coded their version of Zaxxon (1982) in x86-64 Assembly language, and have generously released it as open source under the GPLv3 license. There have been prior UEFI games and apps, but they are often incomplete or limited demos, and run within the UEFI as payloads, rather than booting directly to the game.
