Kill all the renegades inside the base, go down and finish off another group. Open the elevator doors and jump down. Destroy a dangerous group of enemies. Among them there will be one powerful opponent. I recommend go up and killing the archers first. Then go to the truck and watch the cutscene.

You will find yourself at the Renegade’s base. Hide from enemies and move across the grass. Get to the entrance to the desired building. Unfortunately, the enemies are standing right at the entrance, so you have to fight. Once in the building, kill everyone and look for the note (commemorative souvenirs) on the long dining table. Then look for a hatch in the floor, jump down and swim through the water to the stairs. Go through the door to the Colonel, the leader of the Renegades, who will share some very interesting information. You can trust him, and you won't be disappointed, because Jack Matt really went crazy and tried to kill Frank!
Use the elevator and go down to Waltz's room. There are some collectibles here - (cassettes). After collecting them, get out. If you trusted the colonel of the renegades, then he will give you transport. Get in the van and watch the video.
