I know board games are supposed to be played with many payers but as the box mention it can be played solo I tried to do so to test the single player playability of the game with the client set-up.
I must say that as much as I think the game does a good job as a coop card game, (even if I would love more missions and blackmarket options, i'm sure this will come later) this game is hardly playable solo. The biggest issue is obviously the assist cards, wich makes a portion of the blackmarket almost useless and some obstacles and crossfire cards that have a totally destructive effect in 1 player game like for exemple "runners cant play against obstacles facing them". In 2 player game you would play on you friend's obstacle but as you are alone you pretty much lose a turn and take damage.
It's definitely not a rant against the game ! I'm going to play it with my friends a lot for sure but it is a 2-4 player game.
