The LA-based studio behind the multiplayer side of things has been answering fan's questions, from which this little lot has been collected:
■ On the game's player count: "12 is the maximum for PS3/Xbox 360 and 16 is the maximum for PS4/Xbox One & PC".
■ On the release date: "we're committed to releasing with the single player campaign, so no we won't be delaying the launch of MGO".
■ Why the multiplayer won't features the open worlds of the single player campaign: "memory is one thing, multiplayer takes resources. The single player campaign likewise isn't balanced to multiple players".
Camo works like actual camo:
@NaturalSpaceCat camo is helpful like real camo, use it to hide from enemy sightApril 21, 2015
■ There is a skill system, they're just not talking about it yet: "can't detail the skill/skill system just yet, we'll talk about it at a later date".
■ When asked if the US based studio was still working with Kojima: "yes, we continue to work with the staff in Japan". (Hmm...)
■ There's no online trophies or achievements:
@savvyclan0 it means no XBL or PSN based achievements and trophies respectivelyApril 19, 2015
■ They talk about returning features like Team Sneaking mode and customisation: "TSNE yes, customisation yes, can't comment on more yet".
■ There's no non-PvP stuff:
@medenwaldt_ryan sorry, non-PvP content is not plannedApril 18, 2015
So far, what we've seen shows objective-based team missions where rival sides steal/protect assets using a mix of stealth and very MGS tools like retro-styles mechs and.. um puppies. You can also invade your friends Mother Bases, although that seems to be more of a single player thing, putting you against the collected resources and soldiers of your rival.
