Guy Savage

Guy Savage is the name of the nightmare sequence in Metal Gear Solid 3. The game was written and directed by Shuyo Murata. The game is a basic hack-n-slash game where the player encounters a vast amount of enemies, and must press the attack buttons repeatedly to defeat them.

Witnessing the dream
When Naked Snake is placed in the jail cell in Groznyj Grad immediately after being tortured by Volgin, the player must save their game before escaping from the cell. When that save is loaded, the player will be in Snake's dream.

During his conversation with Para-Medic while saving, Para-Medic will talk about the movie Dracula as Snake starts to fall asleep; after waking up from the dream, Snake chastises Para-Medic for giving him nightmares about vampires.

A "Dream" save can be distinguished from a normal save on the memory card: the flower in front of the gun in normally white, but in a "Dream" save, it is red. If the player saves over the "Dream" save (either by progressing in the game after escaping from the cell, or by overwriting the save with another save), the flower on the save file will again be white.

Overview
Snake's dream consists of a large warehouse with destructible walls, zombie-like characters, and a player controlled character holding two hook swords. The zombies, who also each wield two hook swords, will always be chasing after the player.

The player can do a variety of attacks. For example, pressing will make the player spin around with the two swords sticking out, while pressing  will allow them to jump where they can press  to do a downward slash. At certain points during the dream the character will suddenly undergo a transformation in which he turns into a monster himself. In this feral state, the character's strength amplified as he performs more brutal attacks on his enemies. The game will last for roughly five minutes.

There is no objective other than killing the zombies. The zombies will always respawn, resulting in the dream never ending until the player dies or time runs out and Snake wakes up.

Inclusion in Metal Gear Solid 3
It is unknown why the game was included in Metal Gear Solid 3 other than as an Easter egg for players to find. When Hideo Kojima was asked why it was included in Metal Gear Solid 3, he simply responded with "what game?"; he either did not know it was included, or pretended not to know about it. In a later interview he stated that the dream was originally going to feature Gradius, another classic Konami game, but decided that he would rather include an original game.

The game, according to Murata, was supposed to be developed into a full game, but was canceled.
