Six Years in the Making — State of Decay 3 Alpha Playtests Open in May

Undead Labs has confirmed the first community alpha for its long-awaited zombie survival sequel. Sign-ups are live right now — here is every confirmed detail.

State of Decay 3 was first announced at the Xbox Games Showcase in July 2020. For nearly six years, updates were sparse — and with several Microsoft-published projects cancelled in that period, the survival sequel had gone quiet. On April 3, 2026, developer Undead Labs broke the silence with a direct video message to the community and confirmed that a series of Alpha playtests will begin in May 2026. Sign-ups are open now at playtest.stateofdecay.com and require a Discord account and completed survey. The game is in development for Xbox Series X|S and PC, and is confirmed for Xbox Game Pass at launch.

Alpha slots for the first round are limited. Undead Labs confirmed that players who do not get in will be kept on the list for multiple further testing windows throughout 2026. No full release date has been announced. The Xbox Games Showcase on June 7, 2026 is the next scheduled event where additional details on the title are expected.

Franchise History

From Xbox 360 Debut to Alpha Test

The State of Decay series in order — from the 2013 original to what’s happening in May 2026.

June 5, 2013
State of Decay — Xbox 360
Originally codenamed “Class 3,” the first game launched on Xbox 360 on June 5, 2013, followed by PC later that year. It sold over 250,000 copies in its first 48 hours and over 1 million by October 2013, establishing the community-and-base survival formula of the franchise.
May 22, 2018
State of Decay 2 — Xbox One & PC
The sequel introduced four-player co-operative multiplayer and launched on Xbox One and PC on May 22, 2018. It was the best-selling game in the US in its launch month, with sales doubling the original. By August 2021, it had surpassed 10 million players. Microsoft fully acquired Undead Labs around this time, making it a first-party Xbox studio.
March 13, 2020
State of Decay 2: Juggernaut Edition
A free update for existing owners that added a new map, an overhauled tutorial, new weapons, improved graphics, and brought the game to Steam and the Epic Games Store. Undead Labs continued supporting State of Decay 2 with major updates through late 2024 — 38 major updates in total.
July 2020
State of Decay 3 Announced — Xbox Games Showcase
First revealed at the Xbox Games Showcase 2020 with a cinematic trailer. The game was described as being in early pre-production at the time of announcement, planned for Windows PC and Xbox Series X|S.
2024
Gameplay Trailer — Xbox Games Showcase 2024
After years of near-silence, Undead Labs showed a gameplay trailer at the Xbox Games Showcase 2024, confirming development on Unreal Engine 5. Shortly after, the studio announced it was shifting all focus and resources fully to State of Decay 3 as post-launch support for State of Decay 2 ended.
April 3, 2026 — Now
Alpha Playtests Announced — Sign-Ups Open
On April 3, 2026, Undead Labs published an official video message from Franchise Co-Creator and Principal Art Director Brant Fitzgerald announcing a series of Alpha playtests beginning May 2026. Registration is live at playtest.stateofdecay.com and requires a Discord account and completed survey. Multiple testing windows are planned throughout 2026. The Xbox Games Showcase is confirmed for June 7, 2026.
“Over the last few years, most of the team has been doing updates for State of Decay 2. The rest of us have been creating cool [stuff] for State of Decay 3. We’ve been keeping a close eye on what you liked about State of Decay 2 and what you didn’t. We’ve read your feedback on Discord. We’ve watched your gameplay clips and livestreams on YouTube. It became clear that community is survival — and that we need your help.”

Sign Up for the Alpha

How to Register — Step by Step

Undead Labs laid out the exact process in their official announcement. Here is the full sign-up flow confirmed by the studio.

1
Go to playtest.stateofdecay.com
The official registration page for the State of Decay 3 alpha. This is the only official sign-up location confirmed by Undead Labs. You can also find it linked from the game’s Steam page.
2
Connect your Discord account and email
A Discord account is required to register. The Undead Labs Discord server saw high traffic immediately after the announcement was made on April 3, 2026. If you do not have a Discord account, you will need to create one at discord.com.
3
Complete the short survey
Undead Labs stated clearly: “Slots are limited, and we’ll only select players who have filled out the survey.” The survey must be completed — simply registering without filling it in does not qualify you for selection.
4
Refer a friend (optional)
A refer-a-friend option is available at sign-up. Undead Labs has not specified whether referrals improve your chances of selection into the first round.
5
Wait for contact — or stay on the list
If selected, you will be contacted. If not selected for the first round, Undead Labs confirmed: “We’ll keep your name on the list and have plenty of other opportunities for you throughout the year.” Multiple testing windows are planned for 2026.

Alpha sign-ups are open now. Register at playtest.stateofdecay.com with your Discord account and complete the survey. More testing windows are planned throughout 2026 if you miss the first round.
