How to fix Mortal Kombat 1 ‘game session has desynchronized’ error

When playing online in Mortal Kombat 1, you may end up getting disconnected from your match with the following error message appearing on the screen:

The game session has desynchronized.

To see how you can potentially fix these disconnection issues in this fighting game, you can take a look at this troubleshooting article from Seeking Tech.

1. For the first step we suggest taking a look at your internet connection. We recommend doing the following:

  • Pause and downloads or streams that may have concurrently running on the same network.
  • If possible, try to use a wired Ethernet connection instead of Wi-Fi.
  • If you can only use Wi-Fi, then you should make sure that the Wi-Fi signal is strong enough.
  • Power cycle your home networking equipment by turning the devices off, waiting for several minutes and then turning them back on again.

Having a faster internet connection without any congestion may help get rid of most of the desynchronization errors.

2. Make sure you have the latest patch installed for Mortal Kombat 1 if you haven’t done so already.

3. There could also be an issue with the servers. If there are, you will learn about it through the official social media channels for Mortal Kombat, such as its Twitter page.

When it comes to sever problems, you most likely need to wait until the development team fixes the issues before you can play online again without disconnections.

4. If you are playing the game on Steam, then the “game session has desynchronized” pops up frequently in the following scenarios:

  • Playing ranked matches.
  • Selecting rematch.

In these cases, we recommend that you avoid playing ranked matches as well as selecting the Rematch option at the conclusion of the match until there is a new server-side fix and/or patch to install for Mortal Kombat 1.

As a temporary solution, you can try playing online matches with another Steam account to see if doing so will fix the desynchronization.

How to fix input lag issues in Mortal Kombat 1

You may encounter noticeable delays when it comes to pressing the buttons on your controller and seeing the corresponding action appear on the screen in Mortal Kombat 1. To see how you can reduce the input lag for this reboot, you can take a look at this article from Seeking Tech.

1. To start off, we recommend playing the game with a controller or fighting stick through a wired connection. A wireless connection is slower and, therefore, leads to more input latency.

If you are playing MK1 with the DualSense controller on PlayStation 5, then you should plug the controller into USB port of the console and then go to the PS5’s Settings menu. From there, select Accessories > Controller (General) > Communication Method > Use USB Cable.

2. If you decide to stick with a wireless connection, then you should make sure that there is enough battery life remaining as a low charge could lead to the inputs becoming more unresponsive.

You should also make sure that the gamepad has a direct line of sight to the PC or console. Furthermore, avoid turning on other wireless devices near your play area if possible.

3. You should also check the settings of your television screen or monitor.

Make sure that you have the Game Mode picture setting enabled if you haven’t done so already as it will reduce the input delay. You should also avoid turning on any A.I. picture settings, like frame interpolation, as these may add to the latency.

4. In Mortal Kombat 1, you should also make sure that you go to Settings > Kontrols > Input Window Timing. Afterwards, make sure that this setting is set to Long.

By doing so, the game will extend the amount of time it will allocate to recognizing your inputs when it comes to activating special moves. This should be helpful if the latency is messing up your timing.

5. If you haven’t done so already, make sure you have the latest patch downloaded and installed for MK1.

An updated version of the game may fix any of the input lag issues you may be encountering in the fighting game.

How to fix Mortal Kombat 1 HDR and brightness issues

You may notice that the brightness level in Mortal Kombat 1 looks off as some stages look too dark while others look too bright. The levels may also appear to be washed out. To see how you can fix the HDR and brightness issues with this fighting game, you can take a look at this tutorial from Seeking Tech.

1. If you are playing with HDR enabled on the PlayStation 5, Xbox Series X or Xbox Series S, then you should make sure that its output has been properly calibrated for your TV or monitor.

On the PS5, go to its Settings menu and then select Screen and Video > Video Output > Adjust HDR.

For the two Xbox consoles, head over to the Settings menu and then select General > TV & display options > Calibrate HDR for games.

Afterwards, follow the on-screen instructions to see if doing so fixes the brightness issues in MK1.

If you are playing the Nintendo Switch version of the fighting game in handheld mode, then you can try adjusting the screen brightness.

2. You can also use the in-game menus in Mortal Kombat 1 in order to adjust the brightness and HDR levels. In order to do so, open the Settings menu and then select Video & Audio > Calibrate Display.

3. If the colors in the game still look off, then you can try adjusting the brightness and contrast levels in the settings menu of your television or monitor. You can also try changing the different display settings of your screen to see if doing so fixes your issues.

How to find missing Kombat Pack content in Mortal Kombat 1

The Kombat Pack is included in the premium and collector’s editions of Mortal Kombat 1. You can also purchase the DLC bundle as a standalone if you bought the standard edition. If you can’t find the content from the Kombat Pack in the game, then you can check out this troubleshooting article from Seeking Tech.

1. If you bought the physical version of Mortal Kombat 1 Premium Edition, or the Mortal Kombat 1 Kollector’s Edition, then make sure you redeem the voucher that came included in the game box. By doing so, you will be able to download the Kombat Pack.

The digital version of Mortal Kombat 1 Premium Edition should automatically include the Kombat Pack with the initial download.

2. You should also double check to see if you have the Kombat Pack purchased and installed on the digital store front of your platform.

3. Make sure that you have the latest patch installed for the game as a lot of the content from this DLC bundled will be added after the initial launch of the game.

4. You should also make sure that you are connected to the game servers in Mortal Kombat 1 in order to unlock the content.

5. As we stated above, some of the content may not be available yet. For the uninformed, the Kombat Pack comes with the following:

  • Jean-Claude Van Damme skin for Johnny Cage
  • Quan Chi playable character
  • Ermac playable character
  • Takeda playable character
  • Omni-Man playable character
  • Peacemaker playable character
  • Homelander playable character
  • Tremor Kameo character
  • Mavado Kameo character
  • Johnny Cage Kameo character
  • Ferra Kameo character
  • Khameleon Kameo character

When the game was first released (September 14, 2023, for Premium and Kollector’s Edition owners or September 19, 2023, for everyone else), only the Jean-Claude Van Damme skin for Johnny Cage is available. You can find the skin in the Kustomize menu for the character.

The six playable characters and five Kameo characters from the bundle will unlock later after the initial launch date. Once they have been made available, you should be able to access them in the game.

What to do if you can’t unlock Havik and other Mortal Kombat 1 story mode rewards

By playing through the story mode in Mortal Kombat 1, you will unlock rewards. One of the major ones is being able to play as Havik when you beat the entire campaign and reach the end credits.

If the rewards aren’t unlocking for you, then you can check out this troubleshooting article from Seeking Tech.

1. To start off, you should make sure that you are connected to the game servers. Otherwise, you won’t be able to claim your rewards.

2. If you earn the rewards in story mode while playing offline, then make sure you connect to the online servers in MK1. Afterwards, you can claim the bonuses from the Notifications menu in the Kombat Kard screen.

You can open the Kombat Kard screen by pressing the touchpad on the DualSense, View button on the Xbox controller, – button on the Nintendo Switch controller or M key on the keyboard.

3. If you still aren’t unlocking the story rewards, then you can try restarting your game.

On the Xbox Series X or Xbox Series S console, you need to manually quit Mortal Kombat 1 in order to avoid putting it in the Quick Resume queue. You can then open the game again.

4. You can also try replaying the story mode again, with the game connected to its servers, to see if doing so will unlock the bonuses.

How to fix Mortal Kombat 1 crashing issues on consoles

When playing Mortal Kombat 1, the game may end up freezing and booting you back to the home screen menu of your PlayStation 5, Xbox Series S, Xbox Series X or Nintendo Switch console. To see how you can potentially fix these crashing issues, you can take a look at this troubleshooting article from Seeking Tech.

Based on our experience, the freezing occurs after you depleted the opponent’s life bar and just before the words Finish Him appear on the screen. The crashes happen more frequently in the Tower and Invasion modes when playing as a female character.

1. For the first potential fix, you can try deleting the game from the console and then re-installing it.

2. If re-installing the game did not help, then you should make sure that you aren’t putting the game in a suspended state and then putting your console in sleep/rest mode. Otherwise, the game may become unstable when you resume from where you left off.

On the Xbox Series X or Xbox Series S, we suggest that you manually quit the game before you turn off your console. In order to do so, you need to take the following steps:

  • Press the Xbox button on the controller.
  • In the guide menu, move the cursor over to the Mortal Kombat 1 icon.
  • Press the Menu button on the controller.
  • Select Quit from the pop-up menu.

3. You can also try playing Mortal Kombat 1 offline. Keep in mind that some of the modes are online only.

4. Make sure that the game is installed on the console storage if you have the PS5, Xbox Series X or Xbox Series S version. If it is installed on an expanded SSD instead, then we recommend moving it over to the internal SSD.

5. It is likely that a new patch for MK1 will improve the stability of the software, especially with the crashing issues appearing to be common.

Therefore, you should make sure that you have the latest version of the game downloaded and installed.
