This guide is a detailed walkthrough for Checking In, which is the fourth mission of The Last Dose chapter in GTA Online's Los Santos Drug Wars. This mission involves confronting Dr. Isiah Friedlander at a rehab clinic, leading to a drug-induced combat sequence.
In this mission, you need to face Isiah Friedlander at a rehab clinic. You will be asked to follow Dax to the location, but you don't have to follow him. You can simply mark the location and drive to the destination on your own.
When you get to the rehab clinic, kill all the enemies and go to the main entrance of the clinic, indicated with a yellow marker.
