Tower Defense Simulator Events: Kingpin Tower Live Now and What’s Next
Tower Defense Simulator rolled its schedule forward on July 17, 2026: the Semiquincentennial Summer update wrapped at 12:00 PM ET, and the Kingpin Tower event took over the moment it ended. Looking further out, Paradoxum Games has already lined up its next evolved tower — Enforcer — for the middle of August. This page covers Tower Defense Simulator’s current lineup of in-game events — what’s live, what’s next, and a plain-language look at what each one adds.
The game remains one of Roblox’s heavyweight experiences. It has passed 4.8 billion lifetime visits and holds nearly 3.5 million favorites, and there are around 20,000 players in matches fending off zombie hordes as of this writing. Three events sit on the calendar right now: the Kingpin Tower event now live, the summer update that recently closed out, and the Enforcer Tower drop scheduled for August.

Current and upcoming events
Kingpin Tower (live now)
Kingpin Tower is the event live in-game right now. It began at 12:00 PM ET on July 17, 2026 (9:00 AM PT, 5:00 PM BST) and runs through 12:00 PM ET on July 31. The update introduces Kingpin, the evolved form of the Crook Boss tower — a crime boss who bankrolls his operation with cash, backroom contracts, and hired muscle. His roster spans gunners, bouncers, hitmen, and money runners, and his signature ability, Hit Orders, pays out bonus cash for wiping out marked enemies. It is comfortably the most popular item on the schedule, with more than 160,000 players having marked interest — well ahead of anything else here.
Enforcer Tower (up next)
Enforcer Tower is the next event on the calendar, set to run from August 14 to August 28, 2026, both starting and ending at 12:00 PM ET. It continues the evolved-tower theme, turning Shotgunner into Enforcer, a SWAT-styled unit armed with a heavy shotgun and flashbangs that stop enemies in their tracks. Upgrades take the shotgun fully automatic, let players move towers around the map by helicopter, and bring in armored vans that smash straight through enemy lines. Interest is already over 50,000 players — still a fraction of Kingpin’s turnout, but a strong start for an event nearly a month out.
Semiquincentennial Summer (recently ended)
Semiquincentennial Summer was the update that ran from July 3 to July 17, 2026, ending at 12:00 PM ET on July 17 as Kingpin Tower took its place. Themed around both the season and America’s 250th birthday, it added three cosmetic crates: the Beach Crate and Scuba Crate, both made through the game’s Community Workshop, alongside a Patriotic Crate for the anniversary. It drew interest from more than 90,000 players over its two-week run.
A pattern is taking shape across these drops. Paradoxum has been rolling out evolved towers one after another — Kingpin now, Enforcer next — and each event runs for a full two weeks. The handoff isn’t always seamless, though: where the summer update passed straight to Kingpin Tower with no gap, Enforcer doesn’t begin until roughly two weeks after Kingpin ends on July 31. Every one of these events has started at 12:00 PM ET, so that’s the time to watch when a new tower goes live.
