What is a .PHYA file?

.PHYA is a Marathon (Aleph One) file (Games). Analyser identifies a .PHYA file and reads the metadata in its header, right in your browser.

Did you know
  • Marathon keeps its gameplay rules in physics data, which Aleph One loads alongside a scenario's maps, shapes and sounds.
  • Marathon was Bungie's breakthrough sci-fi shooter, first released for the Mac in 1994, with a story-rich design ahead of its time.
  • Bungie released the whole Marathon trilogy as free downloads, so anyone can play the games through Aleph One today.
What Analyser reads
Identify Marathon (Bungie's 1994 FPS trilogy) and Aleph One data files - the open-source engine that runs Classic Marathon, Marathon 2 and Infinity on Steam: scenario maps (.scen / .sceA), physics models (.phys / .phyA), shapes/sprite collections (.shps / .ShPa), sound collections (.sndz / .sndA), recorded-game films (.filA), interface images (.imgA) and MML config XML (.mml). Reads the big-endian wad header version and the embedded internal name from each.
Depth of analysis
.PHYA is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
Open a .PHYA file
Drag a .PHYA file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
