Build and Kill Zombies
Build and Kill Zombies: Hollow Forge Countdown and What’s Next
Build and Kill Zombies keeps a steady rotation of limited-time events going, and the current headliner is Hollow Forge, the second chapter of the game’s Hollow Dungeon storyline. It went live on October 17, 2026, and is scheduled to run through the morning of October 24. Waiting right behind it is a Halloween event, subtitled Trick or Treat, which picks up the moment Hollow Forge ends.
The experience, built by Zombie Car Crusher, hands you a buildable vehicle to load up with weapons and defenses before throwing wave after wave of zombies at it to see how long your creation holds together. It has pulled in nearly 60 million visits and more than 1.2 million favorites, and about about 3,100 players are in it right now.
Exact start and end times for everything on the calendar are in the schedule below. We update this page whenever the lineup changes. Last verified October 22.

Current and upcoming events
Hollow Forge (live now)
Hollow Forge is the event running right now. Billed as part two of the Hollow Dungeon arc, it extends the dungeon-crawling content the developer started earlier in October and leans on how far players can push into it. It opened on October 17 at 10:00 AM ET and closes on October 24 at 10:00 AM ET, with about a day left left before it wraps. More than about 91,000 players have marked themselves interested.
Halloween event — Trick or Treat
Next on the calendar is the game’s Halloween event, subtitled Trick or Treat. It is set to begin October 24 at 10:00 AM ET — the same Saturday-morning slot Hollow Forge leaves open — and run through October 31, wrapping up around 11:00 AM ET on Halloween itself. It is a seasonal, new-content drop built around the holiday, and the developer hasn’t spelled out exactly what it adds yet. Interest is already climbing ahead of launch, with about 45,000 players signed on so far.
How the recent schedule has run
The weekly rhythm is easy to read from the last few weeks. Hollow Forge followed the original Hollow Dungeon event, which ran October 10 to 17 and drew about 130,000 interested players. Before that came Zeus Part 2, October 3 to 10, the biggest turnout of the stretch at over a quarter of a million. Each one opened on a Saturday at 10:00 AM ET and lasted exactly a week, so the Halloween event is landing right on the game’s usual cadence.
