Yes in singleplayer, but not in the same way on every multiplayer setup. A solo game can be paused manually. A dedicated multiplayer server has no player-triggered pause; its PauseEmpty setting can stop game time when nobody is online. In host-run co-op, secondhand guides claim that only the host can pause for everyone, but that behavior is not confirmed by an official developer source. The safest approach is to verify the key binding or server setting in the exact build and configuration you are running.
Pause behavior at a glance
| Mode | Who or what pauses the game | Trigger | Where you control it | Evidence confidence |
|---|---|---|---|---|
| Singleplayer | The local player | A pause key; guides report Esc and F2 | In-game Options/key bindings | Manual pausing is established, but the exact default key can vary by build or guide |
| Host-run co-op | Reportedly the host, for all players | Esc is reported to pause the shared session | Host’s game, not a server ini | Unconfirmed secondhand reports |
| Dedicated server | No player | No manual world-pause command found; PauseEmpty can freeze time with zero players online |
The server’s servertest.ini or equivalent ini file |
The setting is documented by the fan wiki; player pause is not documented in the retrieved material |
These are different systems. A local pause key affects a solo session, host controls affect a peer-to-peer co-op session, and PauseEmpty is an automatic condition for a dedicated server. Changing one does not create the others.

Singleplayer: how to pause Project Zomboid
Try the pause key in the running world
Singleplayer can be paused manually. One guide reports that pressing Esc pauses the game. A separate PZ Manual guide titled “Project Zomboid pause and shout keys: F2, Q and rebinding” identifies F2 as the pause key and says it can be rebound under Options. That F2 detail is a secondhand summary of Build 42.21 bindings, and it was not checked against the in-game menu.
- Load a solo save and wait until you are in the normal gameplay view.
- Press the pause key shown by your current key-binding screen. If you have not checked it yet, test Esc and F2 separately rather than assuming either is universal.
- Confirm that the world is no longer advancing before you step away. Press the same key again to resume at the previous game speed, according to the Build 42.21 summary.
If Esc opens a menu instead of stopping the simulation, that does not prove the game cannot pause; it may mean your build assigns pausing to another key. Use the binding screen as the authority for your installation.

Find or rebind the key
The PZ Manual guide says the pause action can be changed from Options. Menu names can move between builds, so look for the keyboard or key-binding list inside Options and search for an entry named “Pause” or an equivalent action. Assign an unused key, apply the change, and test it in a live solo session. Record the new key if you use a nonstandard layout, because a later reset of controls can restore a different assignment.
Build-specific caution matters here. The F2 reference is tied to a Build 42.21 summary, while the current date is later than that build. An update can change defaults, add a conflict, or alter how Esc behaves in menus. Treat the displayed binding in your client as more reliable than an older web guide.
What pausing does and does not change
The purpose of the local pause is to stop the active solo simulation while you are away from the keyboard. It is not a save operation, a speed adjustment, or a server setting. Resume with the same pause action before continuing. If you need a persistent checkpoint, save through the game’s normal save process separately; do not assume that pressing pause writes a save.
Host-run co-op: why the answer is less certain
Host-run co-op is a peer-to-peer session in which one player’s game acts as the host. The retrieved material says that only the host can pause, that Esc pauses for everyone, and that pausing is unavailable when the host is offline. Those statements come from a secondhand search summary, not an official Indie Stone document or a directly verified manual page, so they should be treated as unconfirmed behavior rather than a guaranteed rule for every build.
If you are the host
- Start the co-op world and confirm that you are the player hosting it, not merely joining someone else’s session.
- Use the pause action shown in your own Options/key-binding screen. Esc is the key reported by the summary; F2 may appear in builds that use the Build 42.21 binding described above.
- Tell connected players that you are testing a pause. Have them watch an obvious in-game activity so you can determine whether the shared simulation actually stopped for everyone.
- Resume with the same action and verify that the session continues normally.
If the test does not pause every player’s view, do not assume a client-side menu pause stopped the world. Recheck which machine is hosting and whether your build has changed its co-op controls.
If you are a joining player
A joining player should not expect to stop the shared world independently. The host-only claim is not officially confirmed, but it is the behavior reported by the available co-op summaries. Ask the host to perform the pause test instead of repeatedly pressing keys on your own client. If the host has disconnected or is offline, the same summary says pausing is unavailable; the session may need to be ended or re-hosted rather than paused.

A host-run game uses the host’s running client and its local controls. A dedicated server runs separately and reads an ini file. A pause key that works in a solo or host session does not provide a pause command for a dedicated server, and changing PauseEmpty does not add a pause button to a co-op host’s interface.
Dedicated servers: the role of PauseEmpty
Players cannot manually pause the dedicated world
The retrieved guides do not identify a player command that pauses or resumes a running dedicated multiplayer world. Instead, they describe PauseEmpty as the server option that stops game time when no players are online. The PZwiki Server settings page shows PauseEmpty=true in its example and describes that value as stopping game time while the server is empty.
That means the setting is occupancy-based: the server can freeze automatically at zero connected players, then continue when players return, subject to the behavior of your build. It is not a moderator’s emergency pause switch while somebody is still connected.
Locate the server ini
A search summary reports these commonly used locations:
- Linux:
~/Zomboid/Server/ - Windows:
%UserProfile%ZomboidServer
Those paths were not verified against an official document and hosting panels can place files elsewhere. Look for the generated server configuration, often named servertest.ini, in the panel’s file manager or in the Zomboid server directory created for your account. If several ini files exist, edit the one attached to the server instance you actually launch.
Set the empty-server behavior
- Stop the dedicated server before editing its configuration so that a running process does not overwrite your change.
- Open the active server ini file, such as
servertest.ini. - Find the line
PauseEmpty=. If it is missing, use the configuration generator or your host’s documented method rather than inventing a second spelling. - Set the value to
trueif you want game time to stop whenever no players are online, orfalseif you want the simulation to continue while empty. - Save the file, start the same server instance, disconnect all players, and check the world after a known interval. Reconnect and verify whether time advanced during the empty period.
Use lowercase true or false exactly as shown in the examples. A panel may expose the same option as a checkbox; in that case, confirm which ini line the panel generated before troubleshooting.
Is PauseEmpty true by default?
There is no reliable single default established by the available sources. Their claims conflict:
| Source or example | Claim about the initial value | How to use it |
|---|---|---|
| Shockbyte guide | Says a fresh configuration ships with PauseEmpty=true and advises checking the value. |
Useful as a hosting-guide claim, not proof for every Project Zomboid build or panel. |
| Low.ms guide | Says the stock default is false; the guide was roughly 49 days old at retrieval. |
Conflicts with the Shockbyte claim, so do not generalize it. |
| Steam guide for Build 38.30 | Lists PauseEmpty=false. |
Very old build-specific evidence and not a current default. |
| XGamingServer example | Uses PauseEmpty=true in an example. |
An example configuration is not a statement of the shipped default. |
Check the value in your own generated ini for the build and hosting environment you use. Do not change it merely because a guide labels one value “default.”
Administration: what setaccesslevel can and cannot do
Administrative access is granted with setaccesslevel <name> admin. It can be entered in the server console or in-game as /setaccesslevel. The retrieved material contains no admin command that pauses or resumes a running multiplayer world.
For pause-related control, the documented choices are therefore limited to:
- Use the local pause binding in singleplayer.
- Test the reported host-only pause behavior in a host-run co-op session.
- Configure
PauseEmptyfor automatic freezing while a dedicated server has no players.
Granting admin rights does not, by itself, add a hidden pause command. Avoid relying on unlisted console verbs copied from unrelated server tools.

“F2 does nothing in my solo game.”
- Open Options and inspect the current key binding for Pause; the Build 42.21 summary is not a guarantee for later builds.
- Check for a keyboard-layout or another-action conflict, then assign an unused key.
- Test in the active gameplay view, not while another menu has focus.
“Esc opens a menu, so the game will not pause.”
Esc is only one reported control, while F2 is another reported control tied to a specific build summary. Check the displayed binding and test the assigned action directly.
“My dedicated server keeps running when everyone leaves.”
- Identify the ini file used by the server instance, rather than a similarly named backup or test file.
- Read the current
PauseEmptyvalue. - Compare it with your intended behavior and change it to
trueif an empty server should stop game time. - Restart the instance after saving and perform an empty-period test.
If the setting is absent or the panel rewrites it, use the host’s configuration editor and confirm the generated file after the next launch.
“Another co-op player cannot pause.”
That result is consistent with the unconfirmed host-only report. Have the host check the pause binding and perform the test. If the host is offline, the same report says pausing is unavailable; reconnecting to an active host is the practical test.
Version and source limitations
All available references for this question are third-party hosting guides, a fan wiki, or Steam community pages. None is an official Indie Stone statement. The F2 binding is specifically presented as a secondhand Build 42.21 detail, and the co-op rules are also secondhand. Defaults and menu labels can change between builds, server panels, and operating systems.
Recommended Free Tools
Use the in-game Options menu for a solo or host session, and inspect the actual generated ini for a dedicated server. Those two checks resolve most uncertainty without assuming that an older guide’s key or default still applies.
Bottom line
Pause manually in singleplayer by using the key shown in your current bindings; Esc and F2 are both reported by different guides, so verify rather than assume. A dedicated server has no player pause control in the retrieved material: use PauseEmpty if the world should stop only while empty, and inspect your own ini because published defaults conflict. Host-only pausing in co-op is plausible from secondhand reports but remains unconfirmed, so test it with the actual host and build you use.
