How to Kill The Tsar Fish and Unlock The Fisherman Achievement in Metro Exodus
During your journey through Russia, you will find yourself in the Volga location, where Artyom will have to do several tasks. One of them is to get a railcar from the abandoned terminal. A few minutes after your arrival there, you will see a huge mutated catfish known as the Tsar Fish. You won’t be able to fight it, but there is still a way to kill the monster.
When you get to the terminal gates, walk inside the room on your right. There, look rtight and you will see a bell, three ropes and a lever. First, cut the ropes to drop dead bodies in the water. Then, ring the bell that cultists use to summon the Tsar Fish. When the monster comes to eat the bodies, pull the lever to turn the railcar bridge and drop the wreckage into the water. The wreckage will kill the fish and you will unlock the Fisherman achievement.
