Metal Gear Solid 3: Snake Eater Easter Egg - Sam and Gabe

If you play the 'Snake vs. Monkey' minigame, at the start of the minigame, when you are being de-briefed by Colonel Campbell, a reluctant Snake says 'can't Sam or Gabe do it?' This is a reference to the 2 main characters from the 2 main rivals of the Metal Gear series of recent years. Sam is 'Sam Fisher' from the 'Splinter Cell' series and Gabe is 'Gabe Logan' from the 'Syphon Filter' series, both games are stealth style games like MGS.
