Chainsaw Ganado behave like any other Ganado, attempting to directly confront the player and strike with their weapon. What makes them so much more dangerous than their lesser brethren is that they have much more health than regular enemies and do not flinch from single Handgun bullets. They walk slightly faster than regular enemies, and their only attack instantly kills the player, but they are also larger targets who can only attack at close range.
Chainsaw Ganado come in three types - "Chainsaw Man"; the "Chainsaw Sisters" and "Giant Chainsaw Man", the latter of whom only appears in "The Mercenaries". The Chainsaw Man's HP varies with individuals at 3000; 4000; 5000 and 6000 HP. The Chainsaw Sisters only appear at 4000 HP. The Giant Chainsaw Man appears at either 3500 or 4000 HP.
Chainsaw Man will approach Leon and if he gets close enough, he will swing his chainsaw at Leon's neck, sawing right through it, if its attack is uninterrupted.
There is another death animation if the player is up against a wall or walking backwards; the Chainsaw Man will slice through Leon's neck while Leon tries to push the saw away, but ultimately ends up decapitated.
Killing any Chainsaw Man is tough, for they have considerable health. Because they don't stagger easily and can cause instant death, the player should stay away and avoid getting near them at all costs. Handguns are not recommended when facing this Ganado.
They are susceptible to being stunned and open to melee attacks from damage to the head, lower legs, or Flash Grenades however, it takes many gunshots to achieve this.
The player can opt to fight with a Red9 if it has firepower upgrades. It should be able to cause stun easier than other handguns or the TMP.
Because of the danger they pose, they player should unload bullets into them even while they are knocked down.
When stunned, they do not flinch out from handgun shots. This opportunity can be used then and fire at them rapidly.
If the player is running toward a Chainsaw Man, be cautious as they may start their chainsaw attack at a distance in attempt to intercept the player. However, this can be taken advantage of. You can intentionally make them miss by triggering their attack. Holding the run button then tapping forward towards them may cause this. During his attack animation, he is affected by handgun shots, so you can headshot him or use any tactic of your choice. This takes some practice to perform well.
On occasion, Chainsaw Men will lift their hands to cover their face if the player is aiming a gun at their head at point-blank range. This is more likely to happen if they stand up off the ground next to the player and are not charging at the player with their saw raised. Advantage should be taken of this opportunity as it allows the player to escape or shoot Chainsaw Men with ease.
You can use knife while they are on the ground and there isn't other enemies nearby. This is dangerous as there is no chance of stunning them again with the knife when they get up. In the Wii Version, the knife is faster and aiming is easier meaning stunning from headshots will now be a viable option.
If the player attempts to leave from the way they came in, one spawns along with two villagers in front of the gate. This one drops 10,000₧. A different one will spawn if the player enters the house with the Shotgun and triggers the cutscene. This one will drop a Ruby. The first one will not appear if the other one has spawned. The second one will replace the first one if he was spawned (It is possible to kill the first one, enter the house, and kill the other one).
