targeting Mike first, Armando continues to assassinate other targets on his list during Mike's convalescence. Following Mike's recovery, he is determined to seek revenge and unsuccessfully attempts to recruit the now-retired Marcus, causing a fall out between them. Mike violently obtains the identity of arms dealer Booker Grassie from an informant. Realizing that Mike will not heed orders to stay away from the investigation, Captain Howard reluctantly allows him to work with the tech-driven team in charge, the Advanced Miami Metro Operations (A.M.M.O.), led by Mike's ex-girlfriend Rita.
