How to fight the octopus head at the beginning of STALKER 2: Heart of Chernobyl
It's best not to hit the octopus head.
After the plot progresses and you get the first artifact, this octopus head will appear. I don’t know what the production team is thinking. The prologue gives us a mid-to-late monster with invisibility, thick skin, and high attack. A proper BOSS in the eyes of novice players. In the veteran difficulty, one claw is left with blood, and two claws rise to the sky.
I was caught alive three times, and finally I found that this guy couldn't jump or climb a ladder, so he could easily avoid it. However, after being caught to death so many times, my temper got worse, so I went back to the research room and found a wall to lean against. Then, after all the bullets were fired and the health pack was exhausted, it was finally worn to death. As a result, the hair on it didn't fall off, and the beard on its mouth didn't sell for me.
Alas, the cost of eliminating harm is too high. It is true that it is not suitable to be a hero in the end of the world. If you meet anyone, just run away.
