On October 28, STALZONE rolled out an update that added the PvPvE event “Celebration.” Five‑player squads start with basic weapons and immediately dive into a fight to protect the Relic from mutant hordes, zombified foes, and rival teams.

The match structure features three PvE rounds, a boss encounter, and a final showdown where the team dealing the most damage to the Altar claims victory. Matches can stretch to 25 rounds, and from the sixth round onward, challenging modifiers appear. Gear is purchased with Yav earned during combat, and each armor type grants distinct tactical options—for instance, scientific gear lets players descend to the Altar through level‑4 bio‑contamination.

From November 4 to 18, a ranked progression system runs with leagues and extra rewards. The top tier “Enlightenment” league will contain only the best 10 % who reach the fifth league, while the elite “Redemption” league is limited to the top 250 players. Wins grant Rubles and Chrysmeniks, exchangeable for weapons, skins, decorations, and more. Weekend bonuses on November 7‑9 and 14‑16 boost rewards by 30 %.
