Canyon Clash

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.

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.
