Resident Evil 4 Remake is a very popular masterpiece. This game is well-made and has novel gameplay, and is deeply loved by the majority of players. Recently, the editor saw that many players encountered the "Resident Evil 4 Remake" Underground Laboratory Executioner BOSS in the game. In order to help you find a solution, the editor has reviewed a large amount of literature. Now I will tell you the correct solution to this problem.
To deal with the executioner BOSS, you need to use a liquid nitrogen spray device. Lead it to the red pipe and press the red button to spray liquid nitrogen.
Liquid nitrogen can slow down its movements, making it vulnerable when frozen. You can choose to use powerful weapons to fight it, or you can choose to avoid it and wait for the elevator to arrive and just take the elevator to leave.
If you want to kill it, then you must cherish the opportunity. The liquid nitrogen spray device will break down when used up, and there are only four of them. You must spray it violently when it is frozen, otherwise it will be difficult to kill it and get the treasure.
After the elevator arrives, even if you don't kill the executioner, you can just take the elevator and leave.
