NASA Space Science Investigations: let's explore the ISS for free... and we mill in 30 minutes!
The aim of the game is to move at zero G in the station, to ensure that the H-II supply transfer vehicle (HTV) is successfully moored to the International Space Station, but not before having prepared the station for the arrival of the vehicle. And as we move around the station, the game will also teach us the effects of microgravity on the human body.
But that's not all: if you are not particularly interested in the topic or in this type of educational experience, you may be interested in the fact that Space Science Investigations will allow you to earn 1000 easy Easy Gamerscore points: all the objectives present are in fact unlockable in about 30 minutes of play.
You can queue the download of the game from this page, or by searching for it in the Store on your console. Have a good exploration!
