Tundra Arms League will begin with the Preview Phase, followed by the Alliance Sign-Up Phase, Elimination Phase, Championship Phase, and will conclude with the Results Phase.

1. Preview Phase: The Saturday and Sunday of the week before the Tundra Arms League begins.

Each Zone can hold up to 64 Legions. If fewer than 16 Legions sign up, the Tundra Arms League won't be held in that Zone.

2. Alliance Sign-Up Phase: From Monday to Saturday during the first week of the Tundra Arms League. This phase consists of the Voting Phase, Sign-Up Phase, and Matchmaking Phase.

2.1 Voting Phase: Monday and Tuesday during the first week of the Tundra Arms League. Alliance members can choose from five battle time slots: 02:00, 07:00, 09:00, 12:00, 14:00 UTC. The voting result is not final; it serves only as a reference for R4/R5 members.

2.2 Sign-Up Phase: From Wednesday to Friday during the first week of the Tundra Arms League.

All Alliances can sign up for this event, but only the top 64 Legions by Power in each Zone will qualify for participation. At the end of the Sign-Up Phase, if fewer than 16 Legions sign up in a Zone, the Tundra Arms League won't be held for that Zone. Alliance Leaders and R4 members can register for up to 2 Legions per Alliance. The number of combatants for each Legion will be calculated separately. After the Sign-Up Phase ends, the combatant list will be finalized. Only Alliances above Lv. 6 with at least 40 members logging in during the first week of the Tundra Arms League can unlock Legion 2.

For combatants, their Furnace must be at Lv. 16 and above, and they can't be offline for more than 5 days before participating in the Tundra Arms League. Only the combatants and substitutes can enter the Tundra Arms League battlefield. Once the Sign-Up Phase ends, no further changes can be made to the list of combatants and substitutes for the rest of the Tundra Arms League.

Alliances with at least one Legion qualifying for the Tundra Arms League cannot be disbanded once the Sign-Up Phase ends and until the Tundra Arms League concludes. An Alliance can be disbanded after all its Legions are eliminated.

Alliances must choose 3 battle time slots from 5 options. The final match time will be automatically selected based on the times selected by both sides. The match time cannot be changed throughout the entire Tundra Arms League once the Sign-Up Phase ends.

2.3 Matchmaking Phase: Saturday of the week the Tundra Arms League begins.

3. Elimination Phase: From Sunday of the first week to the Sunday of the second week. There will be 4 rounds of matches during this phase.

4. Championship Phase: From Monday to Sunday during the third week. There will be 3 rounds of matches during this phase.

5. Results Phase: From Monday to Sunday during the fourth week of the Tundra Arms League.
