About
World of Slime is a casual MMORPG where you capture, collect, and grow with all kinds of slimes. Find new slimes through field capture, synthesis, and fishing, then take them with you into battles, exploration, and puzzles.
Story
You're a young villager who sets out beyond your hometown with your father, only to be separated when a powerful slime attacks. You wake up alone in an unfamiliar village, with no way to know where your father has gone. Taming your own slime companion along the way, you set out to find him and make your way back home — but the journey reveals a much bigger secret: the true origin of the slimes overrunning the world, and why the villages stopped speaking to each other at all. To solve it, you'll need to do what no one else has managed — bring the isolated village masters back together.
What is happening now
World of Slime is a cozy creature-catching MMORPG developed by South Korean studio TEAM42, coming to PC, Mac, iOS, and Android at the end of 2026. The game emphasizes relaxed gameplay around collecting and raising cute slimes alongside other players. Developer activity around the game's December launch has centered on expanding its demo ahead of the full release. A substantial demo update introduced new regions and additional slimes to catch, along with fresh quests. TEAM42 is also bringing the game to Steam Next Fest in late October 2026, giving players another window to try the expanded demo build before the official launch.
