Arena Breakout Infinite Halloween: Mysterious Night Event Guide
The Arena Breakout Infinite Halloween event, Mysterious Night, runs from October 29 to November 25, 2026 (UTC+0).

Mysterious Night turns Farm and Valley into night-time maps with jack-o'-lantern caches and a roaming boss that drops exclusive Halloween keys.
Collect candy from eliminated bots to exchange for the Pumpkin Head helmet skin, a limited weapon charm and Koen bundles.
Keys obtained from the boss open vaults that contain red-tier loot with a significantly higher chance than normal raids.
