Every action in Warfront Nations consumes one of three core resources: **Money**, **Gold**, or **Energy**. ## Currencies ### Money Main in-game currency. Used for travel, market trading, training (slow path), and general economy. Earned from factory work, missions, and World Boss participation. ### Gold Premium currency. Used for: * Perk training (fast path) * Creating factories (200 gold), parties, and states * Revolution wars (200 gold per participant) * Energy drinks, cosmetics, and shop purchases Earned from achievements, daily missions, World Boss, casino, or purchased via the [Premium shop](/guide/premium). ## Energy Energy fuels work, war participation, and World Boss attacks. | Tier | Starting | Max | Regeneration | | -------- | -------- | --- | -------------------- | | Standard | 100 | 100 | +10 every 30 minutes | | Premium | 100 | 200 | +20 every 30 minutes | **Endurance bonus:** `floor(endurance / 25)` extra energy every 30 minutes. So 25 endurance = +1, 50 endurance = +2, etc., stacked on top of base regen. ### Energy Drinks * **Cost:** 100 gold each * **Daily limit:** 3 purchases per day * **Effect:** Restores energy to max (100 standard, 200 premium) ## Storage Resources Raw and crafted materials in your storage: * **Raw:** oil, ore, uranium, diamonds * **Crafted units:** tanks, airplanes, ships * **Consumables:** energy drinks Raw materials come from factory work and can be sold on the [Market](/guide/market-and-crafting) or used in crafting. Military units are crafted from raw materials and deployed in [warfare](/guide/warfare). Don't let energy sit at max — it's wasted regeneration. Spend it on jobs or wars whenever you log in.
