METAL GEAR SOLID V: THE PHANTOM PAIN Infinite Money and Heroism Cheat Mission 20
So get to mission 20, when you reach the hospital at the end, find the two rats shown in the video…….SNEAK UP ON THEM! If they run away just reload the checkpoint and you will start right at these two rats. Tranq. them and pick the one closest to the bed up as much as you want. I earned 670k in about 15 minutes. Just keep picking them up for as long as you want then complete the mission.
