Mycelium

Take control of a fungal colony and spread across the area, dominating other species in Mycelium! Can you spread your spores fast enough?

Welcome to the microcosm where unassuming organisms have their own way of life! Your objective in this game is to spread throughout the level and defeat your opponents. Before you start, you can customize the game options to your liking. You can play the game solo or online, pick a map, adjust its size, and even select the number of enemies. When you start, click on an area to spread there. Your opponents will be spreading too, so make sure to capture as wide an area as you can early on. You can cut off the sections of your enemies' areas and consume them, but your opponents can follow the same strategy too, so watch out. Your colony's heart is represented as a white orb, and if it's taken by an enemy, you will lose. There are various maps, terrain types, and resources. Check the legend on the main menu to plan your strategy! Good luck!
