Metal Gear Solid: Master Collection Vol. 1 is out now on PS5 and PS4, and it hasn't taken dedicated fans very long at all to unearth evidence of yet more Metal Gear ports. According to Timo635 on Reddit, there are clear references to Metal Gear Solid 4: Guns of the Patriots, Metal Gear Solid: Peace Walker, and Metal Gear Solid 5: The Phantom Pain in the PC launcher for the collection's version of Metal Gear Solid 2.
"There's a function for finding the right path to read assets for. They have listings for all the Volume 1 games, but also 4, 5, and Peace Walker, hinting that those may actually be part of the rumoured Vol 2," writes Timo635.
Of course, the 'Vol. 1' part of the name has always suggested that Konami has plans to re-release more Metal Gear titles, but it's still nice to have what is seemingly some degree of confirmation.
For Metal Gear Solid 4 in particular, this could be the dawn of a new age, having long been locked to the PS3. Peace Walker, meanwhile, was unshackled from the PSP when it was remastered on PS3. Both games may finally taste sweet multiplatform freedom in the relatively near future — although it'll be interesting to see just how a port of 4 holds up, given its many PS3-specific functions.
As for Metal Gear Solid 5... well, the game already runs like a dream (on both PS4 and PS5, via backwards compatibility), so we imagine that'll be more of a re-release in Master Collection wrapping than anything.
It's also worth mentioning that these three games were rumoured to be part of Vol. 2 months ago — so it's safe to say that the evidence is really starting to add up now.
