Is this actually a multiplayer only game?. Can't seem to find any info...
From the KS comments:
"BlackFoot Studios about 15 hours ago
The base game is MP only, but we will have some co-op based game types. We will be going into a little detail on those in an update here. So even if we don't hit that stretch goal, you will still have plenty of fun with Ground Branch."
And the description says: "The initial release of Ground Branch will be a robust and unique multiplayer experience that focuses mainly on team-based and adversarial game types."
So, yeah MP only at the start, with SP coming later down the road. But the KS itself is for the initial MP part, if I understand it right.
