# Metal Gear Solid series references
Look at the two puppets dangling from Screaming Mantis. The two puppets appear to be Psycho Mantis and The Sorrow from previous Metal Gear Solid games.

When Snake hides from the two Irvings next to the box of watermelons, the box reads "No Place For Hideo".
You can see a ghost image of Hideo Kojima in Otacon's lab using the camera. It is between Policenauts and the poster that from a distance reads "Final Fantasy VI".
When Snake and Naomi talk about war changing and how it used to be "just a game", all of the Metal Gear Solid titles appear in an indexed list. After Metal Gear Solid 4, there are a few boxes titled "In Production."
# PlayStation 3 references
In the Act 1 briefing, there is a PS3 on the second floor of the plane.
When you send out the MK-2, look over Snake's shoulder by tilting the camera. He is using a PlayStation 3 controller to control it.
After you defat Crying Wolf in Act 4, Otacon calls you as you enter that building and tells you to change discs. He then catches himself, and starts talking about Blu-Ray and the PlayStation 3.
# Snatchers reference
The suit Snake wears in Act 3 is a homage to Gillian Seed, from Snatchers.
# Star Wars reference
In the Act 5 briefing, while Mei Ling is explaining the situation to everyone she says something about it being an impenetrable fortress or something similar. Snake then says, "He has his very own Death Star."
