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.
Current detailed public datasets show Protein Farms adding the same base hourly production amount per level, which supports balanced leveling of available normal farms while cheap levels remain. Exact resource costs can be reduced by player buffs, so use the live building screen for your account’s displayed cost.
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
The modern target version uses the daily Tetris-style Serum Collection mini-game beginning early in Week 1. Clear full rows/columns, especially those containing target pieces, to progress and earn Serum Fragments and Mutant Crystals.
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.
Do not publish a rigid week-by-week purchase ranking until the modern inventory is captured completely.
