Retro Tower Defense Minor Update: Start Time & Countdown

Updated September 9, 2026 By AllThingsHow Staff 2,900 playing now

Minor Update is Retro Tower Defense’s steady content beat — a lightweight patch that brings fan-favorite heroes and skins back into the game on a predictable, repeating rhythm. It is not a one-off event but a recurring slot that comes around every couple of weeks, so there is always a fresh drop on the horizon for the game’s regulars.

Retro Tower Defense is one of the platform’s busier tower-defense titles, holding about 2,900 in its lobbies at any given moment and about 160,000,000 visits to date. That means every Minor Update lands in front of a large, active crowd. The next arrival and the usual window are on the card below.

How often Minor Updates land

A new Minor Update arrives roughly every two weeks, and it has run 2 times so far. The developer, Plaything Games, releases it on a Friday around midday Eastern. The next one is expected Friday, September 18 at 1 PM ET; that date is our best estimate from the update’s usual two-week rhythm, and we confirm it once the developer posts it.

The update goes live at the same clock slot each cycle, which lands at different times around the world. Here is when a Friday noon-ET release falls across the major regions:

RegionLocal time
US West (PT)9:00 AM Friday
US East (ET)12:00 PM Friday
UK (BST)5:00 PM Friday
Central Europe (CEST)6:00 PM Friday
India (IST)9:30 PM Friday
Japan (JST)1:00 AM Saturday
Australia East (AEST)2:00 AM Saturday

What each Minor Update brings

The focus of a Minor Update is returning content rather than a full overhaul. Each cycle rotates previously limited heroes and cosmetic skins back into the game, giving players a fresh chance to add them to a roster:

  • Returning heroes that were only available for a limited run come back into circulation.
  • Cosmetic skins reappear for players who missed them the first time.
  • Because the pool rotates each cycle, what shows up varies from one Minor Update to the next.

Tips for catching it

Pick the window that suits you: the noon-ET slot is midday for North America, early evening across Europe, and late night into the small hours for East Asia and Australia. If your slot is awkward, it is worth setting a reminder for the following Friday, since the update returns on the same weekly cadence. And if you miss a cycle entirely, there is no need to rush — another Minor Update is only a couple of weeks away.

How it fits Retro Tower Defense’s rhythm

Minor Update sits alongside the game’s other regular content. The Weekly Challenge Update keeps a steady challenge cadence going between drops, while larger beats like Map Masteries add new content on their own schedule. Minor Update fills the space in that calendar as the reliable, two-week refresh of heroes and skins, so there is rarely a long gap without something new to chase.
