Fun fact. Many ninjas in the past dressed just like regular people as agent 47 does. Their mission was usually to get info or to infiltrate a heavy guarded place and be close to a big target for years before there is a need to be eliminated.

A perfectly white and well lit room, a ninja dressed in black sneaks about, 10 meters from your face: Huh, must have been the wind.

Guards: "That's 47. I know this guy. To survive, I'd better turn a blind eye to what is happening there."

1:24 "Ooh, piece of candy. Ooh, piece of candy. Ooh, piece of candy...."

1:00 you mean to tell me, that the guard standing there doesn’t care or notice some guy in a ninja outfit sneaking around in the brightly lit corridor?

Ninjas: The secret to infiltrating any well guarded place is to use deception.

Agent 47: Does that mean tossing coins a bunch of times?

Ninjas: Yeah.....Sure. That works too.

Cool part is Ninjas were essentially Hitman of the Japan. They dress like normal people with tasks like infiltration and reconnaissance missions. Their weapon of choice? Exactly what 47 would use, anything they can get their hands on.
So what about the dark uniform and katanas?
They did exist at rare occasions, ninjas did dress in dark blue at night when they are out in the woods as camouflage but only carried gadgets and only enough weapons to use as distractions or in case of emergency. Shurikens where used in training and katanas were rather trophies like how Lugers were trophies in WW2.

I like how you went out of your way to make sure the doctor didn't off himself after he wasn't useful to you anymore

Bro the part at 8:44 where you lay down and get up after the Doctor passes was kinda spooky ngl 🤣 felt like something from a movie

Imagine if IO Interactive did a Ninja game, based on stealth & assassination.

I wonder what a stealth game with actually realistic NPC AI would be like.

"I....woooooohhh!!" Best line ever 4:31

Some people say that ninjas dressed as ordinary civilians. Those people are wrong. The only ninjas that dressed as ordinary civilians are the ones who were bad enough that we know about them. The true ninjas who were never detected always dressed in a traditional ninja uniform, exactly as in this video.

Guard: Oh cool. A ninja ninjaing around.

A ninja does not draw his sword unless he can kill his enemy in one blow.

"Hey, IO, can we have a unlockable ninja outfit so we can RP a Ninja on any map instead of just reskins?"

IO: "Sure, here's a white one with non-funtional goggles, that'll be $60 dollerydoos, please!...Oh wait! sorry that's just the Deluxe pack DLC, you need the $130 Deluxe edition"

why did i feel bad when the doctor got excited and then you changed his neurochip lol

Me - "how many attempts did you have to achieve this result" ?
He - "YES"

Heard a tiny coin drop, from behind a thick thick window, through heavy beeping and steam... Seems legit and hyper realistic.

The level of awareness of the NPCs is comical lol
