DETAILED GUIDE

How it works

Serum Collection

The modern Serum-rollout version uses the daily Tetris-style Serum Collection mini-game beginning early in Week 1. Clear complete rows and columns, especially those containing the target pieces, to progress and collect Serum Fragments and Mutant Crystals. Treat it as daily seasonal progression, not optional side content.

Serum Shop priority

Use a value hierarchy rather than buying whatever is first in the list: seasonal progression resources first when they unlock meaningful progress; profession or other high-value limited progression next; permanent rare progression after that; generic resource and speed-up sinks last.

Settlement warning

The exact end-of-season conversion for Serum Fragments is still version-sensitive. That makes useful purchases safer than intentionally hoarding a large balance for an assumed conversion.
