SEASON 1 · WEEKLY ROADMAP

Day 1 Priorities

The first actions that start the Season 1 progression engine.

ScopeModern Serum rollout

Quick read

Day 1 is about starting production and resistance as fast as practical: Protein Farms → Immune Protein → VRI → Virus Resistance, while clearing new seasonal enemies and beginning profession progression.

Facts

Protein Farms produce Immune Protein used to upgrade the Virus Research Institute.
VRI increases Virus Resistance.
Seasonal enemies and Purge progression provide Mutant Crystals and other progression value.
Check the season calendar for Serum Shop and Serum Collection unlocks; these features may open on different days.

Watch out

Raw squad power is not the only PvE gate; low Virus Resistance can make a strong squad perform badly.
Do not dump Serum Fragments into low-value sinks before understanding the shop.

DETAILED GUIDE

How it works

Page: Season 1 Day 1

Do these first

Unlock and begin leveling Protein Farms.
Push the Virus Research Institute as Immune Protein becomes available.
Kill new seasonal enemies for first-kill / Purge progression and Mutant Crystals.
Start Profession EXP progression immediately.
Open the Serum Shop and understand what it is selling before spending fragments casually.
Leadership begins the Stronghold route instead of taking random land.
Check the Resistance requirement before attacking seasonal PvE targets.

Protein Farms vs VRI

Protein Farms generate the Immune Protein used to progress the VRI. The VRI increases Virus Resistance. Therefore the two systems should be treated as one progression engine, not separate buildings competing for attention.

Upgrade Protein Farms evenly while levels are affordable. Check each farm’s hourly production and account-adjusted upgrade cost before spending.

Resistance warning

A high-power squad can still perform badly against seasonal targets when Virus Resistance is too low. Players should check the target's Resistance requirement instead of assuming the squad-power number tells the full story.

Serum Collection

When Serum Collection is available, complete rows or columns in the puzzle, particularly those containing target pieces, to earn available seasonal rewards.

Do it daily. It is seasonal progression, not throwaway side content.

Serum Shop early priority

Safe early principle:

seasonal progression resources,
profession progression / high-value limited items,
permanent rare progression,
low-value generic resource/speedup sinks last.

Choose Serum Shop purchases based on the items and prices currently shown, not a fixed weekly ranking.
