FOX / BIG BOSS - Elite Achievement Guide - Fast & Easy

By HighRoller

🕵️‍♂️ Technical Stealth Espionage: Big Boss Run Guide
Directed by HighRoller on Steam

This guide outlines four different methods to unlock the achievement for earning either the FOX or BIG BOSS codename. They’re ranked from fast & easy to extreme, so you can choose the challenge level that suits your playstyle.

Playing the Japanese Version (Easy Mode Trick)
To play the Japanese version of the game, you’ll need to download the Japanese language pack:

Go to your game in the Steam Library.

On the right-hand side under DLC, click Manage my DLCs.

Download the Japanese Language Pack.

Once installed, you’ll find the Japanese version listed under the original game. This version does not include a difficulty selection, meaning it defaults to easy mode compared to other regional versions.

No it doesn't count as a continue! So you are safe!

If I land on the continue screen but I back out and load a previous save does that count as continue in mgs1?
