: Solo play encourages "bending the rules" to better suit the story you want to tell.

If an enemy is in base-to-base contact, they will always execute a fight action.

Since the core rules lack an "Opponent AI," the community has developed a widely accepted "AI Flowchart" system. This is often distributed via PDF on community sites (forums, blogs, and Reddit).

If you want to add bounty hunting to your solo campaign, Dead or Alive includes solo rules for tracking marks. It is a good secondary purchase.
