📅 Week 1 – Base Building

Week 1 of Season 1 is all about getting your Virus Research Institute and Protein Farms up and running. These buildings are the backbone of your Crimson Plague resistance and must be leveled every week. Your early decisions here define your power scaling.

🎯 Main Objectives (All Players)

Build and upgrade the Virus Research Institute (VRI)
Construct the 1st Protein Farm and push it to Lv5
Unlock and begin construction of 2nd Protein Farm
Complete season missions to earn Mutant Crystals
Aim for Virus Resistance ~2,000–3,000 by end of the week
Focus on Engineer profession unless already 20M+ squad

🧑‍🌾 F2P Strategy

Build VRI ASAP, aim for Lv5–8 by the end of the week
Complete “Genetic Recombination” and Doomsday events to farm Mutant Crystals
Upgrade 1st Protein Farm to Lv5, unlock the 2nd Farm
If crystals allow, start upgrading 2nd Farm to around Lv3–5
All Immune Protein goes into VRI first, then Protein Farm upgrades
Save enough Immune Protein to continue upgrading into Week 2
Avoid unnecessary spending or unlocking buildings out of order

Engineer advantage:

Passive construction speed buffs
Early access to “Build for Free” skill (Prof. Lvl 10)
Recommended: Stick to Engineer until at least HQ30

💳 Light Spender Strategy

Same priorities as F2P but faster
Purchase Weekly Pass to unlock a second Protein Farm instantly
Push VRI to Lv10+, reaching ~3,000–3,500 Virus Resistance
Level both Protein Farms to around Lv5–8
Use saved Mutant Crystals to push 3rd Farm by end of week
Consider buying a small Immune Protein pack to boost early VRI levels

Engineer bonus:

Reduces Immune Protein cost via profession tree
Unlock free instant builds & shortens speedup usage
Stick with Engineer until T10 units are unlocked

🐳 Whale Strategy

Instantly unlock 2nd Farm via Weekly Pass
Push 1st Farm to Lv10, unlock 3rd Farm, then repeat to unlock 4th Farm
All 4 Farms should be active and around Lv10–15 by week’s end
Push VRI to Lv15+ — targeting 5,000+ Virus Resistance
Purchase Mutant Crystals & Immune Protein packs if needed
Plan for Military Base (Outpost) — begin saving Immune Protein
Optional: Begin preparing alt accounts for resource support

Engineer:

Stick with Engineer for all early building bonuses
Optional switch to War Leader only if you’re already fully maxed (HQ30, T10, 10k Virus Res)
Otherwise, stay Engineer and maximize early advantage
