Taika Waititi’s live-action Akira adaptation doesn’t seem to be due anytime soon, after hitting production delays, but to tide us over while we wait a prototype of an early Akira video game has been discovered.

Akira games were originally due to be published on various platforms in 1995, but were never finished, and it’s only now that a prototype of one of them, for Sega Genesis/Mega Drive, has surfaced, uploaded online by the video game preservation community Hidden Palace.

Unsurprisingly, the game isn’t in full working order (or was simply never completed). This means that it can’t be played all the way through, but individual stages can be selected, Screen Rant reports.

These stages involve gameplay influenced by a variety of other games, including Doom (the section where Tetsuo escapes the hospital) and the 1991 motorcycle racing game Road Rash (self-explanatory).
