Tundra Arms League is a large-scale cross-alliance PvP tournament in Whiteout Survival, structured as an elimination bracket in which alliances field legions of players that compete over several rounds up to a championship stage. It was introduced on 21 August 2025.
Format
A full cycle lasts 18 days: a preview and alliance sign-up period, then an elimination phase of four rounds running from the Sunday of the first week to the Sunday of the second, and finally a championship phase of three rounds from Monday to Sunday of the third week. Only the top 64 legions per zone qualify, ranked by total power. Each alliance may field up to two legions, and a legion is made up of 50 players (30 combatants and 20 substitutes). A legion's members need not come from the same alliance — anyone on the server may be enrolled, so states can pool their strength behind one alliance. R4 and R5 leaders choose three preferred battle slots from 2, 7, 12, 14 or 19 UTC. The tournament runs four elimination rounds followed by three championship rounds, and rankings are based on the net total of points won across all matches.
Registration
Players must belong to the alliance and be assigned a combatant or substitute role before the registration deadline. Once registered they may move in and out of alliances freely, provided they sit in their battle alliance at the moment of the battle. An R4 or R5 also picks three preferred battle slots out of 2, 7, 12, 14 and 19 UTC.
Rounds
The 64 qualified legions are split into four groups of 16. Every round spans two days: predictions on the first, battles on the second. Four group rounds settle the eliminations, then four championship matches decide the zone's champion for the season. A legion still alive after Thursday 23:59 UTC cannot take part in the ordinary Foundry Battle that week.
Net points — a legion's points minus its opponent's — are added up across every elimination match, and they keep counting after a defeat: they set the final legion ranking, and therefore the ranking rewards, even for a legion that never reached the championship.
The four championship legions are split in two. The top two meet in the gold group, the bottom two in the silver group. The winner of the gold group goes straight to the final; its loser drops to a semi-final for a second chance against the winner of the silver group; the loser of the silver group is eliminated and finishes fourth.
Shops
Match stakes are spent in the ordinary shop and champion stakes in the champion shop. The ordinary shop is one of the rare places to find Mithril; the champion shop offers a teleport skin and the event's island building. Island buildings from this event cannot be raised with island general shards — only the pieces themselves will do.
Ranking rewards
March skins and island buildings go to the top four legions only, and the first-placed legion receives a march skin of its own, different from those of the second, third and fourth, plus an extra island building. Alliance rewards follow the same shape: the four group winners of a zone earn a purple alliance banner, a crossed-cannons logo and the league statue, while the alliance that wins the zone adds an orange banner, a tank logo, an upgraded statue and an alliance HQ skin.
Packs
Two sets are sold during the event. The Tundra Arms Pack, on the packs page, holds gems, teleports, march speedups, march recalls, assorted 20% buffs and healing speedups. The Tundra Hero Pack, on the event page, sells Custom Mythic Hero Shard Chests for the state's current hero generation.
Predictions
A prediction system uses two ticket types: Match stakes (purple) for regular matches and Champion stakes (gold) for the championship.
Rewards
Event currencies include Arsenal coins and Mithril, spent in the event shop. Top 4 legions receive 30-day march skins, island buildings (first place receives an extra building), Champion stakes, arsenal coins, Mithril, Fire Crystals and Mythic general hero shards. Top 4 alliances also receive banners, logos, statues and HQ skins, with improved rewards for zone winners.
