How to start Co-Op mode
When starting the game:
From the main menu, select Co-Op mode
Make sure you choose a Main Mission to begin playing together
Once the mission starts, the second player should be able to join and play alongside you
Important:
If you start a side mission first, the game will launch in single-player mode only.
How Co-Op progression works
Once you have successfully started Co-Op through a main mission, Co-Op will generally remain active for most of your playthrough.
All main missions are playable in Co-Op
After starting Co-Op correctly, you can continue playing most of the story together
However, there are some exceptions:
Side missions and single-player content
Not all content supports Co-Op.
Many side missions are designed as:
Time-based challenges
Solo experiences
These will automatically switch to single-player mode
This is intentional and part of the game design.
Common issues and tips
If Co-Op is not working as expected, check the following:
Ensure you selected a main mission to start Co-Op
Restart the mission if only one player appears
Avoid starting with side missions if you want Co-Op gameplay
Make sure both controllers / players are properly connected before starting
