Hideo Kojima og Konami annoncerede tidligere på året Metal Gear Solid Subsistence, en slags remix udgave af det populære Metal Gear Solid 3: Snake Eater, der bl.a. indeholder en omfattende online-del.
Metal Gear Solid Subsistence indeholder også versioner af det originale Metal Gear Solid og Metal Gear Solid 2, der i sin tid blev udgivet på MSX2-formatet. Der vil være masser af forskellige online-modes heriblandt Capture, Rescue og Team Death Matches.
Hideo Kojima sagde følgende ved annonceringen:
"Finally it is possible to battle with players from around the world online at Metal Gear Solid from the comfort of your own home. For the online mode, the essence of Metal Gear Solid is retained, with additions of various online rules and original stages. With the continued growth of the culture of Metal Gear Solid, this new online addition, I believe will bring a new way to enjoy and experience the world. I hope fans will look forward to experiencing it."
