Metal Gear Solid 5 The Definitive Experience has been dated, and it's coming pretty soon.
This set was rumoured a few weeks back and has now been confirmed. It will contain The Phantom Pain (obviously!), prequel Ground Zeroes and multiplayer madness Metal Gear Online. You'll also get plenty of DLC and currency for your Mother Base.
And all of these goodies are arriving soon enough on the 13th of October, 2016.
There's plenty of DLC for all three games, you can see a list below.
That's a generous package, and it sounds like the box could retail for around €50, which is reasonable considering this content has been out for a good long while already.
