Snake's Dream

Snake's dream is a secret in Metal Gear Solid 3: Snake Eater.

Witnessing the dream
When Solid Snake is placed in the jail cell in Groznyj Grad immediately after being tortured by Volgin, players must save their game and then turn their PlayStation 2 off. The next time players load their file, they will be in Snake's dream.

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

The player can do a variety of attacks. For example, pressing O will make the player spin around with the two swords sticking out, while pressing X will allow them to jump where they can press O to do a downward slash.

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

Inclusion in the game
The game is believed to be Guy Savage, a game Konami was working on at the time though has since stopped development. Shuyo Murata was the game's director.

It is unknown why the game was included in MGS3 other than a little easter egg for players to find.
