Progression, resources and optional purchases
Progress comes from a working economy, informed battles and permanent upgrades. The campaign can be completed without a purchase.

Invest in production and storage
Steel funds structures and units, oil fuels military development, supplies support recruitment, and credits fund many upgrades. Production continues while you are away until storage fills. Check an upgrade's costs before committing, and leave reserves to replace battle losses.
Industrial efficiency rewards development
Production buildings and HQ funding grow with their level. Levels 1–5 use the base output per level. Each level after 5 also adds a cumulative 22% efficiency multiplier, so later upgrades give larger hourly gains. The upgrade preview shows the actual increase. Research, assigned officers and temporary production boosts apply on top; this underlying efficiency is available to every commander without a purchase.
A path beyond the frontier
HQ 8 completes the base-development portion of the campaign; Headquarters can reach level 20. Develop a Warehouse alongside expensive upgrades. Its first five levels add 5,000 capacity per level; after level 5 its total contribution also grows by 40% for each additional level. One fully developed Warehouse can hold the cost of any maximum-level building upgrade without VIP. This makes long-term growth reachable; you still need to produce, gather or earn the materials.
Permanent rewards at your own pace
The eight Frontier Campaign orders grant materials and 190 War Bonds. After claiming them, the ten Veteran Campaign orders lead to HQ 20 and grant another 450 War Bonds. Each reward is claimable once, in order. There is no campaign expiry or requirement to attack another player. Beginner and progression missions offer additional one-time goals.
Daily objectives are optional
Daily missions reset at midnight UTC. They are extra opportunities rather than a requirement for the campaign. A missed day does not erase your permanent campaign progress or remove your buildings and research.
Check reward storage before claiming
Material rewards are limited by available storage. The Missions screen warns when some materials may not fit, and the result shows what you actually received. War Bonds use a separate balance and do not consume material storage.
What purchases change
The shop offers optional currency, time savings, resources, reinforcements, officer crates, shields, extra construction capacity and fixed-duration VIP passes. Some purchases accelerate progression and can affect military strength. They are not cosmetic-only, and purchases do not guarantee victory.
Know what you are buying
Review the complete contents and price in the shop and confirm the purchase before paying. Officer crates have random results; their rarity odds and guarantee are displayed separately. VIP passes show their duration and do not renew automatically. The starter pack has a one-time account limit, not an expiring countdown.
Your first orders are waiting.
