Survive The Swarm: Halloween Season Start Time and Countdown
Survive The Swarm’s next headline event is almost here. Halloween Season opens on Saturday, October 24, 2026, kicking off a month-long run of raid bosses and guild bosses in the solo-made roguelike, and about 13,000 players have already flagged it as one to watch.
The experience has pulled in about 17,000,000 visits and about 140,000 favorites, with roughly about 1,300 adventurers in a session at any given time. Developer FAKT has shipped a fresh event almost every week through October, so the exact dates and start times for each one sit in the schedule below.
A second event is live alongside the Halloween build-up: the Singularity Limited Event, a limited-time gear drop that runs until October 27. Last updated October 22.

Current and upcoming events
Halloween Season
Halloween Season is the headline event on the calendar. It begins October 24, 2026 at 12:00 PM ET (9:00 AM PT, 5:00 PM BST in the UK, 6:00 PM in Central Europe) and runs for about four weeks, closing on November 21. The developer’s notes point to raid bosses and guild bosses as the centerpiece, continuing the co-op boss fights that have anchored recent updates. With early interest already strong, Halloween Season ranks as one of the game’s bigger events this month, and the full window is listed in the schedule above.
Singularity Limited Event
Running in parallel is the Singularity Limited Event, which hands out the Singularity gear set and its Rift Reaver weapon for a limited stretch. It began September 27 and closes October 27 at 1:00 PM ET, so there is about 5 days left left to claim the set. Interest here is modest next to the headline events, which fits its nature as a cosmetic-and-weapon drop rather than a full content update.
Recent updates and the weekly rhythm
The run-up to Halloween shows how briskly FAKT pushes updates. The New Reckoning Boss event opened October 3 with an exclusive drop for players who beat it. A week later, the Class Combat update — billed by the developer as the biggest update yet, adding left-click attacks — went live on October 10 and drew the largest crowd of the stretch, nearly 28,000 interested, alongside a companion New Boss and Class Combat event that layered in a new reckoning drop and a class-abilities overhaul. Most recently, the Guilds, Boss, Weapons event ran October 17 to 21 with exclusive guild weapons and the Medusa Reckoning boss, pulling in more than 23,000 sign-ups.
Those dates line up to a roughly weekly cadence, with new events tending to start in the early afternoon UK time — either 14:00 or 16:00 UTC, which is 10:00 AM or 12:00 PM ET. If that pattern holds, the next drop after Halloween Season should surface within a week or so of the previous one wrapping.
