Evaluation
Zombie Survival Online launched on April 29, 2021 as a free-to-play multiplayer game. In its first few weeks, the developer was very active, posting frequent balance patches, bug fixes, and quality-of-life improvements throughout May and June 2021. On June 15, 2021, a new playable character ("Rich") was added as a major content update, accompanied by a paid DLC on June 17, 2021 allowing players to donate and unlock the character. That DLC is the only one listed for the game, and it has been released.
The developer's last communication of any kind was on June 15, 2021 — nearly five years before today (June 23, 2026). The entire update history is confined to a roughly seven-week window immediately after launch. An earlier post from May 11, 2021 mentioned plans for Mac/Linux builds, custom keybinding, a boss monster, and additional character DLC, but none of those plans materialized based on the available evidence, and the developer has been completely silent since mid-June 2021. With no developer communication since June 15, 2021 and no unreleased content listed on the store, the game appears to have concluded its active development cycle with the June 2021 character DLC. The earlier promises were never fulfilled, but given the extended silence of nearly five years, those plans were not carried through and there is no outstanding commitment the developer is actively working toward.
Evidence
The only DLC — 'Add Character - Rich' — was released on June 17, 2021. No unreleased DLC exists.
Major content update adding the 'Rich' character, the last developer communication on record.

About this game
ZS Online is a top-down 2D shooting multiplayer game that you can enjoy in less than 10 to 16 minutes. Pick up the materials during the day, and make the weapons and items you want! At night, the view becomes narrow and zombies come out. The number of zombies increases every day, and poisonous gases hit the city.
Players can pick up materials scattered across various buildings in the city.
You can harvest trees and fruits.
The map shows the position of the other player, and if you enter the house, you will not be able to see the opponent.
Hunger decreases, and the faster you move, the faster you decrease. When hunger reaches zero, your stamina decreases, and you can eat food to make up for it.
You can combine the ingredients to make weapons, such as knives and guns, or throw tools, armor, and food.
It gets dark at night, and the view is limited, and zombies come out. You will also lose sight of other players on the map.
As the days go by, the number of zombies increases, and poison gas hits the city.
If there is only one player left on the map, you will win.
Choose a character with multiple abilities and play it.
You can also play by yourself without the Internet. In this case, zombies come out during the day, and more. Also, poison gas does not hit the city and scores points.
