cant get him to spawn in been at it for 3 hours now lol
Fight your way to the elevator that causes enemies to spawn when you activate it and has a button next to it that drops a turret. When you kill all the enemies, head to where DJ Tanner spawns during Freedom of Speech and they should spawn, but only if you haven't been to that spot on that run through. Just do what I did and snipe them from the platform with the ladder that takes you back up from that "island".
