This game is nothing short of spectacular. There are a few nitpicks I have with it, like with any game, but overall it is a highly enjoyable play.
If you like open-world games, detailed weapons customization and quirky characters, then you will love this game. The main plot is solid, and the visuals are stunning.
I think the dialogue can be a little too exposition-y but that hardly impeded my enjoyment. If you aren't into open-world games, you probably won't love this as it is a massive map with so many different areas to explore. A lot of the quests can get repetitive after awhile as they are largely based on back-and-forth retrieval for items that characters require, but with a game that looks the way this one does, its hard to complain.
In conclusion, Biomutant offers a vast and colourful world with bizarre and amusing characters. I am eagerly awaiting any potential sequel game that may come out in the future.
