1) the word "Gaijin" means "foreigner" and is meant to be insulting.
2) you never see yourself nor do you have a single line in the entire
game.
3) there are actually several legends that say ninjas can freeze time.
4) in the mission Tetsuo's Games, you can hear the famous
Rayman: Raving Rabbits scream in the security room after the elevator
before you turn the power back on.
5) despite being called "RED Steel" there is no blood in the game. Or
at least not any human blood. In the mission "Fish Market" if you
shoot the hanging fish and blood will fly everywhere.
What weird things have you found?
