You are back in Stilwater, although Zinyak saw to it to do a little redecorating for his simulation. While talking with Kinzie, feel free to steal a vehicle and start driving to your destination, which is going to a shop. Kinzie will tell you to open your map and place a beacon, so follow the directions on the screen to do just that.
Once you manage to get to the Friendly Fire store, enter it and buy both a weapon and upgrade for that weapon. You only have 1,000 Cache at the moment, so it might be best to start off with a pistol, although you should have enough money to purchase a shotgun and SMG as well. Exit the store and you’ll find some friendly company waiting for you.
Kill all of the enemies there and then follow the radar to the next objective, which is called a Flashpoint. This is moreorless a spot that is guarded heavily by Zin troops. When you happen to find these, certain Zin will be marked and you will have to kill all of them in order to capture the Flashpoint.
Capturing the Flashpoint will grant you some extra Cache and respect and once you’re finished, grab another vehicle and head towards the Kinzie’s place. When you get there, you find nothing and find out that Zinyak has removed all signs of the Saints from the simulation. With that, the mission will come to an end.
