Mycelarium Ending: The Great Migration

Mycelarium (the 2026 incremental game by PLAN KAPKAN) names its ending The Great Migration. The achievement text is one sentence: finish the game by a great migration. The studio has not published the trigger.

What is confirmed

The name is on the achievement list added in update 1.02, and it is painted on the task panel in the official surface screenshot, next to the line about five magic mushrooms. So the ending is a goal from the first minute of an Exploration save, not a secret menu. Survival mode’s patch note removes end goals, so this achievement is not available there.

A long play video reaches a moment where the speaker says they are ready for the great migration and then that they can release spores. That is one run, and the same video never reaches the million-centimetre growth achievements. I will not treat that video as a 100 percent clear.

Three player reports, still side by side

Discussion posts do not agree. One says the ending animation plays after the corner task chain is done. Another ties it to planting or firing a large number of spore mushrooms, and the figure “100” shows up as a guess. A third talks about releasing spores once the network is ready. The community ending guide prefers the task-chain reading. I am printing all three because collapsing them into one checklist would hide the disagreement.

Until a store post or a second on-screen tooltip names the trigger, the honest instruction is: play Exploration, follow the corner tasks, find the five magic mushrooms, and read the ending page again when a newer public source picks a winner. I am not listing numbered steps.

Questions people ask

Does Survival have an ending?

The patch note says Survival has no end goals. The migration achievement belongs to Exploration.

Is 100 spore mushrooms required?

That figure is a player guess. It is not in the achievement text.
