📅 Week 3 – Base Building

Week 3 is where base building meets war prep. This week you’ll unlock the powerful Troop Specialty Bases — one for each troop type (Tank, Missile, Aircraft). You’ll need to decide which to focus, based on your main squad.

🎯 Main Objectives (All Players)

Unlock and upgrade Troop Specialty Base for your main troop type
Push Virus Research Institute toward Lv25+
Ensure all Protein Farms are active and around Lv12–15
Reserve Immune Protein for your Military Base (Outpost) if participating in cross-server war

🧑‍🌾 F2P Strategy

Focus on one Troop Base (e.g., Tank) — upgrade to Lv5–10
Bring VRI to Lv20–22 (~7,000+ Virus Resistance)
Keep Protein Farms around Lv12 and balanced
Use Mutant Crystals from events to unlock/upgrade 3rd or 4th Protein Farm
Prioritize Virus Resistance over Troop Base if you’re falling behind in resistance

Engineer Benefits:

Still great value — helps with high-cost upgrades and speed
Stay Engineer until late unless you’re war active and squad power is 20M+

💳 Light Spender Strategy

Upgrade main Troop Base to Lv10–15 for +10–15% buffs
Push VRI to Lv25+ for ~9,000 Virus Resistance
All 4 Protein Farms should be built, target Lv15 each
Consider saving Immune Protein for deploying an Outpost next week
Use Build for Free (Engineer skill) on cheap upgrades or secondary farm leveling

Profession Tips:

Engineer still optimal for build scaling
Switch to War Leader only if you’re battle-ready and have already reached:
- VRI 25+
- Troop Buff Building 10+
- HQ30 & T10 troops

🐳 Whale Strategy

Max main Troop Base to Lv20–30 for massive +30% stat bonus
Max VRI to Lv30 (hit 10k Virus Resistance cap)
Push all 4 Protein Farms to Lv20+ and balanced
Save 1M+ Immune Protein for Military Base (Outpost) deployment
Use this week to finish any lagging secondary base buildings

Profession Tip:

Likely already switched to War Leader for PvP
Optional: Swap back to Engineer briefly to speed up a building rush if needed
