So I'm playing in solo with the 3 AI teammates. I know to press Q while aiming down the sights to mark a target on Sync shot, then hold Q or shoot to engage.
I can't mark more than 1 target though using Q, so between myself and 1 AI teammate can only take down 2 at a time. Am I doing something wrong, missing something. Is the skill upgraded or only with MP. I'm not sure, anyone else having this problem or can help?
