I've not used it but there also appears to be an option in custom games to set a "No delay password" so if there was going to be a referee then they can have no delay but anyone else would have one.
I dont think that there will be MP stuff with AA. The only thing near MP will be coop missions and even that is not 100% sure.
I would like to know tho what the "Rangers Thing" is.
Oh! Actually, I remember someone asked Quinn about that after the stream ended at EGX and all he would say was that some of the stuff from Ardennes Assault would "probably" make it to multiplayer. Didn't commit to anything though. :-(
So two things. A. what are ability trees, and B. what are specializations. Are there somthing new to multiplayer or only for the campaign. something that people should be told before they put money down on it.
I'm pretty sure the Ability Trees are the "Commander" abilities for the different Companies you can play as. I'm not sure about the specialisations, I don't remember them being mentioned at EGX.
These are some great maps! :-P Played a few last night and really enjoyed them.
Only criticism from me was that (at the beginning) The Intersection was super, super green. Faded as the weather changed and became much less...vibrant. Still, didn't effect how fun it was to play. :-P
