Best Campaign Mode Builds

Campaign mode is story-driven gameplay with set loadouts or limited customization in many missions. You can use whatever weapons are provided by each mission or choose the strongest available options, such as M4-style Assault Rifles and versatile weapons. Therefore, prioritize adjusting the difficulty settings  and completing objectives rather than optimizing the meta.

Simply choose the best Assault Rifle or versatile weapon available in each mission and enjoy the story. Meta loadouts and Operators matter much less in Campaign mode.
