SAS Zombie Assault timeline: browser origins to Resurgence
Last checked 2026-10-29. Claims link the source that supports them.
The series begins with SAS: Zombie Assault in 2008 and reaches Zombie Assault: Resurgence in 2026. Browser tests, mobile launches and Steam ports are different events. The table keeps those event types separate and links each date to its supporting record. Sources were reviewed October 29, 2026; a date is marked single-source when no independent confirmation was established.
Release and service timeline
| Date | Event | Evidence and scope |
|---|---|---|
| 2008 | Original SAS: Zombie Assault | Series wiki and independent Web Design Museum agree on the year; no exact launch day. |
| January 21, 2009 | Original game’s Kongregate listing | Kongregate, single platform record; not the 2008 origin date. |
| June 22, 2009 | SAS2 | Wiki, single-source historical day. |
| August 6, 2009 | SAS2: Insane Asylum | Wiki, single-source release announcement date. |
| March 24 / June 6, 2011 | SAS3 closed / open beta | Wiki, single-source; its update list also says June 7 for open beta. |
| December 21, 2011 | SAS3 iOS release | US Apple record, single platform source. |
| February 14, 2013 | SAS TD iOS | US Apple record, single source for this platform; not a claim about the first Flash release. |
| October 23, 2014 | SAS4 iOS | US Apple record, single platform source. |
| October 16, 2017 | SAS4 Steam port | Steam, single platform source. |
| July 8, 2020 | Ninja Kiwi Archive on Steam | Steam collection listing, single source for this launch. |
| January 12, 2021 | Ninja Kiwi website Flash games stop working | Publisher Flash notice, single publisher source; separate from server retirement. |
| April 30, 2022 | SAS3 web and SAS4 web service end | Publisher announcement and wiki account; wiki derives its date from the announcement, so one originating source. |
| October 28, 2026 | Zombie Assault: Resurgence | Steam and US Apple record agree; two store records for the same publisher release, not independent historical reporting. |
Why some dates and totals disagree
SAS3’s 2011 browser beta and iOS release are different milestones. Its wiki also contains an internal June 6 / June 7 beta-date inconsistency, so that exact day remains unresolved. Likewise SAS4’s 2014 iOS date and 2017 Steam date describe different editions rather than a three-year disagreement about one launch.
Map inventories are also version-dependent. The SAS3 guide preserves the iOS description’s five maps, Android’s seventeen and the wiki’s fifteen/twenty wording. A later port does not guarantee all maps or network features from another edition are present.
What happened to the browser games?
Flash support ending in browsers and Ninja Kiwi retiring server services were separate events. The April 2022 announcement specifically names SAS3 web and SAS4 web, including Archive. It directs readers toward mobile counterparts. That notice does not establish a blanket shutdown of every mobile or native edition, nor does it diagnose SAS TD’s historical Establishing Uplink message.
Ninja Kiwi Archive remains the publisher’s collection reference; the wiki inventory catalogs the early SAS titles. Catalog inclusion and functioning legacy online services are different claims.
Where Resurgence fits
The published 2026 title is Zombie Assault: Resurgence. It uses a subtitle rather than the name SAS5. Read the SAS5 explainer for that naming question, or use the individual game pages for current public store links and edition-specific guidance.
Questions on this page
When did the original SAS Zombie Assault come out?
The series wiki and Web Design Museum place it in 2008. Kongregate’s own listing date is January 21, 2009; that is a separate platform record.
When did SAS3 come out?
The wiki dates its browser open beta June 6, 2011, but also lists June 7 in its update history. Apple dates iOS December 21, 2011.
When did SAS4 come out?
Apple dates iOS October 23, 2014; Steam dates its port October 16, 2017. These are different platform launches.
What happened to SAS3 and SAS4 web?
The publisher announced the end of those web services from April 30, 2022, including Archive. The notice does not establish the same outcome for native editions.
When was Resurgence released?
Steam and the US Apple record agree on October 28, 2026. These are publisher store records, not two independent historical accounts.
