The last at least somewhat major video game release of 2021 is Thunderful Games' upcoming The Gunk. It is developed by the Swedish studio Image & Form (known for the SteamWorld games), and here we get to explore an alien world.
Now we've got a new video which explains this strange world and also gives us an understanding of the story, where the two scavengers Rani and Beck have landed on a planet in search for alien plants and resources - only to discover that some thing is very wrong. The Gunk launches on December 16 for PC and Xbox and is included with Xbox Game Pass from day one.
