I just started playing with my son this week. We actually make a good team and have won more duos matches than we've lost so far, which really surprised me.
We're still figuring out all the little tricks to the game, like the upgrade stations and the NPCs. I didn't realize how in depth everything is and will pay attention to see the changes as we keep playing.
and then... theres "building", a whole 'nother "game" inside of the game... takes a lot of skill to master
