It took me and a friend 45 hours to 100% the game. If you are looking for a fun coop game to play with your friend, this is a good one. I will say though, without spoiling anything, make sure to kind of take your time when drilling your caves. Smooth is fast!

I will say that there were some weird achievement things where we had to go back and do something over again for me because it didn't register the first time like for the scanner things. We had to make 7 more and do them for me, which wasn't a huge deal but I feel like we shouldn't have had to do that. Just make sure you both or all of you do the proximity beacons because it is local-based.

Overall, fun experience and I thought the trains were the coolest part of the whole thing. We only built two train systems but especially on the home planet, it was convenient to go get some materials that we needed.

Make sure to invest in good power structure!
