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

Check the Serum Shop for the current stock, purchase limits and any refresh timer. Prioritize items that unlock useful seasonal progress, then limited permanent upgrades. Buy ordinary resources or speed-ups with any balance you can spare.

Settlement warning

Before the shop closes, check what happens to unused Serum Fragments in the settlement panel. Spend on items you can use before the deadline.
