Call of Duty: Modern Warfare 4 is here, and the developers at Infinity Ward and elsewhere at Activision are actively working on future updates. While updates will always include new additions, there are also a number of issues that the developers know need to be fixed.
To keep open the transparency with their players, the studios have a publicly accessible Trello board. The first publication of the board included seven issues. As more issues are discovered, the team will continue to update the board. Once addressed, these issues will be part of future Call of Duty: Modern Warfare 4 updates.
When they are confirmed resolved, they will be removed from the list below.
Insider Gaming will also update the issues below as needed, so make sure to bookmark this page for future reference. If you are having issues, let us know below or in the official Insider Gaming Discord.
