Quick answer

Tyrannosaurus Tex is a historically interesting homebrew for Game Boy Color, originally unreleased and later revived by Piko Interactive. It offers a unique first-person shooter experience on the GBC, but its difficulty and niche appeal mean it's best for collectors and retro enthusiasts who value rarity over polished gameplay.

What makes Tyrannosaurus Tex special?

Tyrannosaurus Tex was originally developed by Slitherine Software and set to be published by Eidos Interactive for the Game Boy Color, but it was never officially released. In 2015, Piko Interactive acquired the rights and managed to recover a full beta version in 2016. This means the game you can buy today is based on that beta, giving you a rare glimpse into a lost piece of GBC history.

The game features over 20 levels, each increasing in difficulty, and uses a first-person shooter perspective that pushes the Game Boy Color's technical limits. For a handheld that rarely saw FPS titles, this makes Tyrannosaurus Tex a standout curiosity.

Trade-offs to consider

Because Tyrannosaurus Tex is based on an unfinished beta, the gameplay can feel rough around the edges. Expect steep difficulty spikes and a lack of modern quality-of-life features like save states or adjustable controls. This is not a casual pick-up-and-play title.

The game's rarity and backstory add collector value, but the actual gameplay may not appeal to everyone. If you're looking for a polished, mainstream GBC experience, this likely isn't it.

Decision rules for buying Tyrannosaurus Tex

  • Collector value: If you value owning a rare, once-lost GBC title with a fascinating backstory, Tyrannosaurus Tex is a strong addition to your collection.
  • Gameplay expectations: If you want a challenging FPS with over 20 levels that pushes GBC hardware, this delivers. But be prepared for beta-era difficulty and no modern conveniences. The difficulty ramps up quickly; consider if you enjoy retro challenge before purchasing.
  • Price consideration: At a catalog price of USD 31.49 (compared to USD 44.99), it's reasonably priced for a niche homebrew. Compare to other GBC homebrews to see if it fits your budget.
