The five death row convicts have come to the United States and Frank wants to take them out. He has info on each convict to form strategies and is working alone. He will go after each one individually with as much prep as he decides he needs and has access to weapons that are grounded in reality like he usually uses.
Bonus: Frank has to take on all the convicts at once but he gets to pick the place and has only two days to prep.
Bonus bonus: What happens if Frank has random encounters with each convict while he's out killing lesser criminals? Can he survive these encounters?
