An odd one to start with. The first nine are free, look for Cube Escape collection. There’s a narrative that runs through and will make the other entries make more sense.
It really should be part of the title of the game. Outer Wilds: don’t look anything up, just play it.
I very nearly had to use a guide at one point but I stayed strong as everything I’d read said I’d regret it if I did. So glad I didn’t as the joy of discovery in this game is unparalleled. Top 5 gaming experience of all time, I reckon.
