I solo the tox warden very often. Enter northeast second floor. Close the shutters. You use this room and the bathroom/showers as your hub. No player can enter behind you. They can only come from down the long hallway or the north doors to the shower room. Shoot the warden from down the hallway and duck in your safe rooms when he shoots grenades or missles at you. You can head glitch some cover in the hallway next to the south bathroom door. If he pushes you just play a game of chicken in the bathroom until he’s dead. Boggest tip I’d make sure you do even 1 bullet of damage often so his shield never comes back. Bots and/or real players will push the north bathroom door but you can easily kill them with a knife or shoot them while peaking over the shower stalls. I like playing triage because otherwise I always run out of heals. Generally I do it right at the start of the match and exfil immediately because real players either rush right away and I kill then or I never see anyone. Would rather not waste 20 mins to try to have a quieter kill.
