Where to Play League of Legends Swarm: Full PvE Mode Breakdown
You can’t play League of Legends Swarm anywhere right now. Swarm was a limited-time PvE mode inside the League client, live from July 17 to August 19, 2024, during the Anima Squad summer event. Riot has not brought it back since: no 2025 or 2026 patch notes mention it, and there is no standalone version, mobile port or console release.
Where was League of Legends Swarm played?
Swarm lived in the normal League of Legends client on PC and Mac, in the game mode selection screen next to Summoner’s Rift and ARAM, for as long as the event ran. No separate download, no extra launcher. You picked “Swarm | Operation: Anima Squad”, chose a difficulty and a champion, and either queued alone or invited up to three friends from your friends list.
The timing was precise. According to the patch 14.14 notes, the mode went live on July 17, 2024 at 15:00 UTC for EUW, EUNE, RU, MEA and TR, and at 18:00 UTC for every other region. Patch 14.16 carried the last call (“your last chance to play our newest game mode”), and on August 19, 2024 Swarm left the rotation. That’s the whole run: three patches, a little over a month.
So when a current guide tells you to “open the PvE tab and click Swarm”, it’s describing an event that ended long ago. The tab isn’t there.
Is League of Legends Swarm coming back in 2026?
There’s no official sign of it. We checked the patch notes for the summer windows where an event mode would appear in 2025 that means 25.13 to 25.16, in 2026 it means 26.12 through the current 26.21, and none of them mentions Swarm. Riot also hasn’t announced a return in its news posts. Could it come back one day? Sure, Riot has revived event modes before, but nothing published right now points to a date.
Funny enough, the signal to watch is simple. If Riot does bring it back, the patch notes will say so a patch ahead, the same way 14.14 announced the original launch with exact times.
What was Swarm in League of Legends?
Swarm was League’s take on the bullet heaven genre (think Vampire Survivors with Anima Squad skins). Riot described it as “a chill, co-op PVE game mode” where you and up to three friends fight waves of Primordians and a boss at the end of each map. Movement used WASD instead of right-click.
Your champion’s basic weapon fired on its own or could be aimed manually, with a toggle to switch between the two. As you killed enemies you leveled up mid-run and picked new weapons and upgrades, and the gold you earned carried over between matches to buy permanent power-ups. Failing was expected. Riot’s own launch tips said they’d be “honestly surprised (and incredibly impressed)” if anyone cleared the missions without losing a few runs first.
Swarm maps, bosses and difficulty levels
There were four maps, each harder than the last, and three difficulty levels: Story, Hard and Extreme. Each map ended in a boss fight. The patch 14.15 notes name two of the bosses, Primordian Rek’Sai and Bel’Veth, and one of the maps, The Beachhead. Beating a map on a difficulty opened the next one and pushed the story forward.
Swarm champions and how they unlocked
The roster had nine playable Anima Squad champions. Patch notes from the event mention Briar, Seraphine, Leona, Riven, Aurora and Yasuo by name, and Aurora was brand new at the time (she launched alongside the event). You started with a few and unlocked the rest through achievements, which also opened new weapons and augments and, for some, gave permanent rewards on your League account. Yuumi appeared as part of the augment pool rather than as a regular pick.
Swarm at a glance
How a Swarm run actually played out
A match started with one weapon and a lot of open ground. Riot’s advice was to walk the whole map, because pick-ups were scattered around it and grabbing them early made the later waves manageable. Every few levels you chose an upgrade: a new weapon, a stronger version of one you had, or a passive. Weapons could evolve. In practice that happened once the right pieces lined up, and it’s where most of the build variety came from. With friends, the champions’ kits stacked together, and Riot openly encouraged testing rosters to find combinations that worked. Did a solo player stand a chance on Extreme? Yes, with enough permanent power-ups bought from earlier runs. That loop of losing, spending gold and coming back stronger was the whole point of the mode.
What Swarm players kept after the event
Not everything vanished on August 19. The permanent account rewards earned through Swarm achievements stayed on accounts, as did any Anima Squad skins bought during the event. The Anima Squad Event Pass, which offered chromas, borders and emotes, closed with the event, so those pass rewards can’t be earned anymore. Riot even ran an in-person pop-up in Toronto on July 12 to 14, 2024, where visitors could try the mode before it went live in the client.
For a quick reference, here is everything Riot confirmed about the mode in one table. Anything not listed here, such as exact weapon counts, came from fan wikis rather than Riot.

Why did Riot make Swarm a limited-time mode?
Riot built it as the centerpiece of one summer event, and event modes in League usually leave when the event ends. Look at the design goal Riot gave: a low-pressure mode where friends of very different skill levels could play together, something Summoner’s Rift is bad at. That’s a great fit for a summer event and a hard thing to keep fresh year-round, since a PvE mode needs new maps and bosses to stay interesting, while PvP modes refresh themselves through other players.
There’s also a business angle, to be fair. The event shipped with an Anima Squad pass and skins (Battle Bunny Aurora, Battle Bat Xayah, Battle Lion Leona and others), and those sold during the event window. Riot has never said Swarm was retired for good. It simply hasn’t been scheduled again.
What to play in League of Legends instead of Swarm
No PvE mode in the client today plays like Swarm, so the honest answer depends on what you liked about it. If it was playing with friends of mixed skill, Co-op vs AI and ARAM are the lowest-pressure options and are always available. If it was the build-crafting with augments, Arena is the closest cousin when it’s in rotation; our Arena tier list covers which champions do well there. ARAM on the Howling Abyss is the other casual favorite, and our Howling Abyss guide explains how that map works.
Put simply, keep an eye on two dates if you want to catch a return early. In 2024 Riot revealed Swarm on June 21 and launched it on July 17, almost four weeks later, with the exact start times printed in the patch notes for 14.14. A comeback would most likely get a similar reveal before it lands, so a summer event announcement in June is the moment to start paying attention. Until then, any video or article that promises a specific return date is guessing.
Outside League, the genre Swarm borrowed from is big on its own. Bullet heaven games on Steam and mobile scratch the same itch, though none of them have the Anima Squad cast.
Real talk: if you are waiting for a League of Legends Swarm return, the only reliable place to watch is the official patch notes, which come out every two weeks. New accounts can’t play event modes early either, so there’s nothing to prepare beyond having the client installed.
