DMZ - My FINAL Season 4 Mission: Chemist Sources | GAMEPLAY

You know what they say "No plan survives contact with the enemy", I found this to be true doing this last mission. It was my last mission before Season 4 finished and it was an uphill struggle from start to finish. All I had to do was find the Chemist and then find a gas sample... how hard can that be? Well watch on and find out.
