Updated: 30th May 2025 1 min read

Riot Games introduced a new cooperative PvE mode, Swarm, to League of Legends on July 17, 2024, as part of the Anima Squad 2024 event. This mode was available until August 19, 2024, offering players a fresh gameplay experience distinct from the traditional Summoner’s Rift.

What Is Swarm?

Swarm is a four-player cooperative mode set in the futuristic Anima Squad universe. Players assume the roles of reimagined champions, known as “fighters,” to combat waves of enemies called Primordians. The gameplay draws inspiration from bullet heaven titles, emphasizing survival against overwhelming odds.

Gameplay Mechanics

Controls: Unlike the standard point-and-click mechanics of League of Legends, Swarm utilizes WASD movement controls, with options for manual or automatic aiming.

Objectives: Players navigate through four distinct maps, each culminating in challenging boss battles.

Progression: As players advance, they unlock new abilities, power-ups, and additional fighters, enhancing replayability.

Playable Fighters

The mode features a roster of nine champions adapted for the Swarm experience:

  • Jinx
  • Seraphine
  • Leona
  • Illaoi
  • Briar
  • Yasuo
  • Riven
  • Aurora
  • Xayah

These fighters are unlocked through gameplay progression, with some available by default and others requiring specific achievements.

Reception and Future Prospects

Swarm received positive feedback for its innovative approach to League of Legends gameplay, offering a cooperative experience that diverged from the traditional competitive modes. While the event concluded in August 2024, Riot Games has expressed interest in exploring similar PvE experiences in the future, taking into account player engagement and feedback.

For players who missed the event, it’s recommended to stay tuned to official League of Legends announcements for potential reruns or new PvE content inspired by Swarm.
