Metal Gear Solid mod makes Grey Fox fully playable in the PS1 classic

Full text

A modder has made Grey Fox playable in the original Metal Gear Solid, and it's way more impressive than it sounds.

Despite Snake (and Snake, and Snake, and Snake, and…) being a contender for the greatest video game character of all time, Metal Gear has a variety of side characters that all absolutely rule, and many hope for the chance to play as them. And while there's been the odd opportunity to play as whoever isn't the main protagonist of a given game (Tanker and Snake Tales in MGS2, Ocelot in Metal Gear Online), Metal Gear is pretty strict about having you play as the main character.

One such legendary side character is Grey Fox, who – after appearances in the MSX2 originals – appeared in Metal Gear Solid 1 as the series' first Cyborg Ninja. The character was so popular that he was the selling point and cover star of Metal Gear Solid: VR Missions, where he was briefly playable for a couple of missions. And while Hideo Kojima wanted the character to get his own game as a sequel to Metal Gear Rising , it never materialized.

However, Grey Fox is finally getting his day in the cold alaska moon, as YouTube user Perfect Pizza has released a first look at the final version of their "Playable Grey Fox mod" for Metal Gear Solid. On first read this may not sound that impressive, perhaps the thought of "oh they just moved the VR Missions character into the main game," crossed your mind? Well this mod is not nearly that simple.

Watching the trailer, right away you'll notice you have access to Grey Fox's arm cannon, which saw use throughout Metal Gear Solid, but never actually got used in his previous playable appearance. The High Frequency Blade has gotten a buff too with a new trailing effect and the ability to ricochet bullets back at enemies, and there's new movement options with crouch walking introduced. The mod promises a ton of changes, like "automatic open and close face visor upon alert,""custom animations," and "custom codec calls".

On the mods Discord , Perfect Pizza explains "This mod uses the PSX decompilation project’s ability to modify the game’s C code and build a new executable using the developer version of Metal Gear Solid." Adding "At the time of creation, neither the AI Grey Fox boss nor the playable VR Ninja have been fully decompiled. As a result, everything shown so far has been recreated through reverse engineering, existing game code, experimentation, and educated guesses."

They explain, "The goal is to let players experience an expanded version of Grey Fox vs what was given to us in VR missions with as many of his signature abilities and some new ones as the game’s limitations allow, while preserving core gameplay features such as crawling, elevators, weapons, and environmental interaction." and that "This project also lays the groundwork for a future version that could allow players to experience the entire game as Grey Fox."

Perfect Pizza also says "This is not a complete story-mode conversion" but that "A separate project, which I am not affiliated with, is working toward making the full campaign playable by rebuilding all the stage overlays and making the compiled exe shiftable. The future of a complete Grey Fox playthrough depends heavily on that effort."

Regardless it's an impressive mod that actually allows playable Grey Fox found in VR Missions to live up to the version we hoped he would be all along, and even if a full version doesn't show up, it'll be fun to play about with.

After almost 25 years, Metal Gear Solid 2 players are still finding secrets: "This is the kind of stuff somebody posts on an online forum in 2005 and no one believes it"
