Bunker Base

A Forward Operating Base that's built directly into a Bunker network. It provides Infrastructure for nearby connected Bunker and Trench segments

Construction
The Bunker Base is built by upgrading a tier 1 bunker with a Construction Vehicle for 300 Basic Materials. The bunker must be part of a large bunker with at least 5 additional bunker pieces (any tier, any upgrade). The bunker we're upgrading must also not be adjacent to a bunker garrison. For a bunker base tier 2 and 3, the prerequisites are the same as other Forward Bases (small Garrison Facility for T2, large for T3) except that for Tier 3 the Bunker Base must also have unlocked the "Concrete" infrastructure Upgrade. Tier 2 upgrade costs 100 bmats, Tier 3 costs 50 Concrete Materials.

Bunker Base Upgrades
Bunker base Upgrades contain the same upgrades as other forward bases but also have two additional upgrades trees ("Garrison" and "Command") to unlock bunker specific upgrades. Those bunker upgrades also require Infrastructure, which is provided by building Infrastructure Modifications in Bunkers. There are two types of Infrastructure: "Garrison" and "Command", one for each upgrade tree.

Unlock order (Assuming you are solo player)


 * 1) T1 AI (5-30mins)
 * 2) T2 AI (13 hours-1day)
 * 3) T1 RG (5-30 mins)
 * 4) T3 AI (2 days +- half)
 * 5) T2 MG + T3 ATG ( 1 day)
 * 6) T1 concrete (1 day)
 * 7) T4 HG (2 days +- half)
 * 8) T2 Deployment point (3 days)

Once an upgrade for a specific bunker garrison is unlocked, bunkers that are connected to the bunker base via trenches or bunkers can be modified to become that specific bunker garrison type (if they don't already have a modification installed). The maximum range of the bunker tech is 40 connected bunker/trench pieces. Once a particular bunker has been modified into a bunker garrison it won't lose its modification if its connection with the bunker base is severed, it can even still have its tier upgraded.

Tips

 * Once an upgrade that required Infrastructure Modifications is unlocked, removing the infrastructure modifications won't make you lose the upgrade or the ability to build the new bunker upgrade type.
