It's coming to iOS and Android on December 1st and, yes, is all about diving through the insides of planets.
You play as a daredevil who travels to different planets with her robot buddy and trusty wingsuit as part of a thrill-seeking adventure.
The fall isn't the biggest of her problems, though, as that belongs to all the nasty fauna and flora that don't appreciate her hobby.
As you'll see in Planet Diver's trailer, there are huge worms, giant eyeballs, and all manners of overgrown creepy-crawlies to tackle during your descents.
You also need to collect as much "star stuff" as possible so you can fund an adventure to an even more distant planet. It can also be spent on upgrading equipment and special abilities.
Plus, if you should need a competitive element while playing Planet Diver, it has online leaderboards and regularly issues you with challenges to complete.
Sound good? Alright then. Planet Diver comes out on December 1st as said. Check out its website for more details.
