In Panzer Waltz you must manage and upgrade the various facilities in your base if you want to progress in the game and develop advanced tanks and technologies. Levelling up your facilities also provides you access to certain features, such as work (or lifestyle).
Upgrading the headquarters is essential to base development as other facilities require a certain HQ level to be upgraded. You must meet a certain commander level to upgrade, and upgrades are expensive and lengthy.
Upgrading the HQ increases the base silver capacity, the maximum amount of petrol you can hold and the petrol produced per hour.
Upgrading the silver mine increases the maximum number of silver coins the mine can hold, and it increases the number of silver coins mine per hour.
The more silver you have held in the mine, the more silver you will lose when a player clashes against you and wins.
Upgrading the silver vault increases the maximum amount of silver coins you can hold in total.
Upgrading the iron mine increases the maxmium capacity of iron the mine can hold, and increases the amount of iron produced per hour.
Iron can be spent at the source or material forge.
The naval port is a facility that periodically provides tanks, food, equipment and other valuable resources. Each item can be purchased with silver, and the number of items brought in each time is determined by the level of your port. A level 1 port has 5 slots, and a level 8 port has the maximum of 12 slots.
Stock will automatically refresh after a number of hours, but you can receive a number of emergency requests (the number determined by the port level) each day. Emergency requests cost an increasing amount of silver, and bring a new wave of stock. Alternatively, you can refresh the stock for 60 iron.
The service station produces milk, and upgrading it increases the maximum milk capacity and the amount of milk produced per hour.
The service station also unlocks the lifestyle/work feature after Volume 6 Chapter 2. This allows you to send your maidens out on various jobs in an attempt to gather food, silver or precious resources.
The BWMG Depot can be unlocked at HQ level 12, and can produce different pieces of equipment and even metal maidens.
Upon unlocking the BWMG, you also unlock three new resources: Iridium, Tritium and Dextrose (IRID/TRIT/DEXT. These resources are slowly produced over time (amount depends on your BWMG level) but also have a chance of dropping in certain chapters. Unlocking the BWMG also grants access to catalysts. Catalysts are used to speed up the refactoring process and regenerate slowly over time.
Unlocking the BWMG also unlocks new options in the store, allowing you to purchase boosts/quantites of DEXT, IRID and TRIT with gold, and exchanging these resources along with corn for crafting materials, food, milk and fuels.
The level of your BWMG Depot determines the blueprint level of any produced maidens:
- Level 1 BWMG produces maidens up to N4 blueprints
- Level 2 BWMG produces maidens up to N5 blueprints
- Level 3 BWMG produces maidens up to N6 blueprints
