Tommy Thunder was a game in development by Player 1. It eventually moved to the PlayStation before getting cancelled. A fan or Robotron happened upon an open FPT while trying to find out when Robotron 64 was released and found some files, eventually cracking them 10 years later and discovering this very early prototype of Tommy Thunder.

This prototype mainly seems to be a test of the level design, as you can just move around and enemies don’t harm you – you also walk on water. That said, the level itself is very impressive in scope, with a few underground areas. This map was also just one “block” and the developers were trying to figure out a way to load new chunks of the level on the fly – this is something open world games do now, but was extremely ambitious for the early N64.

From the very few quotes about the game, it seems like this game was going to be a 3D, open world Metroidvania. You would find weapons as you explored, and equipment (such as anti-grav boots) would alter how you can move throughout the environment, opening up new areas in previous sections. The game never made it past prototyping stages and the company eventually closed down after putting all of their eggs into the Sega Dreamcast.

Should it be finished?

With retro-inspired games for this era gaining popularity, it would definitely be interesting to see a “what if” take on if the developers could pull off what they wanted with Tommy Thunder.
