Just brought my friend into EDO and got some "features" never seen in solo.
While scaveging the settlement every player in the same team can download the same data from the exact same data port and so do the power regulator in broken SRVs. Might be useful for material farming.
For defence missions: it seems more enemies will spawn depending on player count. More fun of course.
And players on board my ship won't get any bounty or bond share in ship combat which is pretty annoying.
