Campaign uses a 25-energy tank that recovers one energy every ten minutes. Entry costs rise along the route, level-ups refill the tank, and Arena does not use Campaign energy. This meter is separate from battle energy.
Plan around entry costs
Campaign attempts spend entry energy. The cost increases as you progress through the route, while early tutorial encounters have exemptions. Check the cost shown for the encounter before starting a series of retries.
Recovery adds one energy every ten minutes up to the tank’s capacity. At that base rate, recovering a fully empty 25-energy tank takes 250 minutes if you do not spend any energy or receive another refill during that time.
Use the other progression options
Inventor level-ups refill Campaign energy. Arena is a separate destination and does not consume this entry resource. While waiting for recovery, you can review your loadout, compare parts and use Arena to explore how a build behaves.
Optional energy-reward ads are part of the game’s documented design, but availability depends on the live build and provider support. Use only the options actually shown in your game. Do not plan progression around an unavailable ad placement.
Keep the two energy systems separate
Battle energy is the battery resource used by weapons and some support effects inside a fight. It regenerates according to the body and build. Campaign entry energy controls whether you can start a Campaign attempt and does not make a laser fire faster.
If you can enter a fight but the weapons stop attacking, inspect combat resources, range and facing. If you cannot enter the encounter, inspect the Campaign meter and displayed cost. This distinction prevents spending Scrap on equipment to solve a waiting timer that equipment cannot change.
