The Alliance Duel is a competitive, multi-day event in Last Z: Survival Shooter where alliances earn points by completing daily tasks like modifying vehicles, using golden wrenches, killing creeps, gathering resources, researching tech, and training or healing troops. Each day focuses on a different set of tasks, allowing players to plan their actions strategically. By scoring high individually and as a team, players can unlock up to 9 reward chests packed with valuable items such as hero badges, orange skill books, enhancement alloys, and more. Aligning these tasks with the Full Preparedness Event can double rewards, making the Alliance Duel one of the best events for progression and ranking.
