The Gunk is a relatively short action adventure experience. You explore a mysterious alien planet in search of energy and uncover an even more mysterious history. During your adventure, you will meet new characters, some friendly and some not, collect resources, solve environment puzzles, and upgrade your abilities. A search for energy brought you here, but the search for the Gardener will keep you here!
The Gunk consists of 8 chapters, connected by a semi open world, withs ome linear paths. You'll need to search most areas for materials to upgrade your abilities (All In (50G)) and scannable objects to add to your encyclopedia (Space Archaeologists (50G)). Along the way, you will find opposition in the gunk monsters and the gunk itself. There are a number of combat related achievements; for using certain abilities (Three's a Crowd (25G)) or getting gunk beasts to run into each other (Take Charge (50G)). The rest of the achievements will unlock as you progress through the story.
If you are thorough enough, you will complete the game with all achievements earned; however, it is ciompletely possible that you still need to scan objects for Space Archaeologists (50G). Luckily, the game's final autosave is just before the final boss fight. And you can leave the area and search the entire map for any scannable objects you missed.
Aside from the Space Archaeologists (50G) achievement, this game is a nice leisurely action adventure game. The game is not particularly challenging and should only last a few hours for completionists. This is an easy and enjoy 1000 to add to your collection!
