Well, Ground Zero is a base game, rather than a DLC. More specifically, Ground Zero is the first game, and Phantom Pain is the second, and together they form the whole of Metal Gear Solid V.

Metal Gear Solid V: Ground Zeroes is the first segment of the ‘Metal Gear Solid V Experience’ and prologue to the larger second segment, Metal Gear Solid V: The Phantom Pain launching thereafter.

The nature of their release makes them less base game + expansion, and more to the vein of Final Fantasy sequels [eg, X + X2, or XIII + XIII-2 & 3]. So even in a more inclusive sense of DLC, it's not really something I'd associate to it [hence my not thinking to address that interpretation of your comment in my previous post].

But yeah, figured even if you already had things sorted on your side, my noting the nature of the DLCs would possibly help someone else who saw your mention of DLCs and needed more info on them. :)

It does include ground zeroes, which I also have a giveaway for! The DLC are almost all cosmetic except for Cloaked in Silence which adds maps for the multiplayer.

Gotcha, thanks for the info!
