Now Mission 46 will take a ton of work, but don’t lose sight of your goal. You must complete every single campaign mission in the game (1-45, 47-50). After that, you must complete every single Side Op that is denoted by a yellow mark. After all of that, you still aren’t out of the woods yet. Metal Gear Solid V: TPP refuses to relinquish this mission without players devoting all of their time.
After completing every mission in the game, you must grind and upgrade your Mother Base as much as possible. Continue to pour your hard earned GMP into your Mother Base until Mission 46 is finally unlocked.
We won’t spoil Mission 46 for you, but suffice it to say that completing this extremely challenging operation will answer a lot of questions for those who were left a bit confused at the end of Metal Gear Solid V: TPP. So get to work and find out what you’ve been missing.
