Co op games are awesome. What's better is that games in general have been making a big come back due to a resurgence of board games in what we now call ‘modern board games.’ What sets this particular game apart is that it utilises an app which transcends the typical rules of a board game. Now, the app acts as the brain of the game. In return, you get to experience something unlike any games that have come before it.
I won't spoil anything so will leave it there.
To the people on the fence or offended that you need an app to run the game: give it a try. It's actually very cleverly done.
Buy this now. You won't regret it!
