Unsure if multiplayer or campaign though.
looks cool hopefully it is a map
May be multiplayer. would be pretty cool. If its campaign then i can only imagine the things we will find.
In order of probability:
Campaign?
Spartan Ops?
Forge environment?
Multiplayer map?
it probably is a multiplayer map because in the backround the orbital elevator looking thing is a dead giveaway, you can just toss one up on requiem in that little time and think about the resources, multiplayer map for me, but it looks very eye catching, would love to see some machinimas on there if its multiplayer
