Metal Gear Solid 2: Sons of Liberty HD Edition Easter eggs

Anger Pliskin
In the big shell after first meeting vamp and pliskin/snake, shoot pliskin/snake with the socom until the ammo runs out, his cone on the radar will turn red and he will shoot at you when your in his sights.
To stop him simply equip the m9 (if you have it) and shoot him with it he passes out and you continue as planned however if you don't have the m9 run away from him and just continue with the game.
