A monthly three-alliance battle on the Lost Canyon map, where Fuel decides how much you can do.

**TL;DR:** Budget your **Fuel**, take buildings as a team, assign Guardians early, and save enough for the Frozen Citadel at the end.

## Key facts

- **When:** Monthly, battle on Thursday
- **Battle:** 60 minutes
- **Size:** 3 alliances per map
- **Needs:** Top-20 alliance, Furnace 16+

## Event week

| Days | Stage |

| Saturday – Sunday | Voting on battle time |
| Monday – Tuesday | Registration |
| Wednesday | Matchmaking |
| Thursday | **Battle** |

Note: From the official help center. Some community guides say Saturday; trust the in-game schedule.

## Battle phases

| Phase | Length | Focus |
| --- | --- | --- |
| Preparation | 3 min | Position your squads |
| Seize & Conquer | 17 min | Capture neutral buildings for points |
| Fortress Occupation | 20 min | Contest the high-value Fortresses |
| Citadel Onslaught | 20 min | Fight for the central **Frozen Citadel**, the top-scoring objective |

## Legions & eligibility

Your alliance must be in the **top 20 by power**. Players need **Furnace 16+** and must join before registration.

Up to **2 legions**, each choosing its own time slot, and rewards are counted separately. Each takes up to 30 combatants + 10 substitutes (15 combatants minimum). The second legion needs **Alliance Level 6** and at least **40 members** active that week.

Players offline for 5+ days normally can’t be newly dispatched.

## Fuel, Guardians & revives

**Fuel** is spent to deploy, conscript, advance, retreat and instantly revive. It regenerates over time.

R4/R5 can appoint **Guardians** to held buildings for more fuel income. A chief garrisoned in an eligible building can appoint themselves, and each player can guard one building at a time.

Defeated squads revive at your **Bastion** on a timer, or instantly for fuel. Leaving the battle starts a **12-minute** re-entry cooldown.

## Strategy

- Save fuel for the **Citadel Onslaught**. It’s worth the most.
- Split targets across the alliance so everyone isn’t rushing the same building.
- Hold chokepoints and buildings rather than chasing kills.
- You score **personal merit** too. You need at least **10,000** for personal ranking rewards, and alliance rewards depend on final placement.
