What is it?
Three seasonal buildings — Tank Base, Aircraft Base, Missile Base — each boosting one vehicle type. Confirmed Mechanic
When does it happen?
They unlock Week 3, Day 1 and require VRI Level 30 to build — reach VRI 30 by Week 3 or you can’t build them at all. Update-Sensitive
Who can start it?
Individual progression. Every player.
How does it work?
Each base gives +1% HP, Attack, and Defense per level for every hero of that vehicle type, to a maximum of Level 30 — up to +30% across the whole formation. Built with Mutant Crystals and Immune Protein. Confirmed Mechanic
What should I prepare?
VRI 30 reached by Week 3 (the hard gate), and a settled choice of primary formation type.
How do we win?
Build and max the Military Base for your primary formation type first, and never split upgrades equally across all three — the most common mistake here. Corroborated Strategy
Common mistakes
- Not reaching VRI 30 by Week 3 — the bases stay locked.
- Splitting upgrades across all three types.
- Building a base for a type you don’t actually run.
Leadership protocol
Remind members that VRI 30 gates the bases, and push the primary-type-first discipline so nobody dilutes the buff. Leadership Protocol
+1% per level across 30 levels is +30% to your entire formation — but only if you concentrate it. Split across three types and you get three mediocre buffs; pour it into your primary and you get a real one. VRI 30 first, then one base to 30.
