Heist of the Lost Isles is Aniimo's headline seasonal PvPvE mode. Matches use a 3-player squad, with real-time searching for high-value egg caches and live combat against both environment enemies and rival squads. Reward structure and rank system are not announced as of 2026-08-29.

3-player squad basics

Each Heist match uses a 3-player squad. The squad moves together through the Lost Isles region, splitting only when objectives call for parallel searches. ComicBook.com preview coverage describes the squad as the natural combat unit; solo play is supported through the open-world PvE loop rather than Heist.

Real-time search and battle objectives

The core Heist objective is real-time searching for high-value egg caches scattered through the Lost Isles. Squads compete against rival squads for the same caches while environment enemies pressure both teams. The combination of PvE threat and PvP competition defines the mode's pacing. The reward structure, including rare unlocks, currency payouts, and rank-based bonuses, is not announced as of 2026-08-29.

Role and element tips for Heist squads

A balanced Heist squad typically includes one DPS, one healer or support, and one Break or Regen slot. Element coverage matters because both environment enemies and rival squads lean on a mix of elements, and matching element coverage can swing the fight in close encounters. For more on the role and element taxonomy, see the [Aniimo elements and roles](/elements-and-roles) page.

Lost Isles region

Heist matches play out in the Lost Isles region, a separate map from the Idyll continent. Astra is the social hub for the broader Idyll area, but Heist of the Lost Isles has its own map and objectives. Region-specific tips are covered on the [Aniimo Idyll regions](/idyll-regions) page.
