PS2 SUBSTANCE FACTS:

1)There is a little bit of extra cinema that has been re-integrated back into the Sons of Liberty game itself for North America (old to Europe, new to North America)

2)European Extreme Difficulty is available (UNLOCK by completing Tanker-Plant once under any difficulty)

3)The USP Suppressor is available on the tanker's crows nest (UNLOCK by completing Tanker twice under any difficulty)

4)You can see Snake, Pliskin and Raiden in sunglasses throughout the SOL game (UNLOCK by completing Tanker twice under any difficulty)

5)Casting Theater is available (UNLOCK by completing Tanker once under any difficulty)

6)Boss Survival is available (UNLOCK by completing Tanker once under any difficulty)

7)358 VR missions, 153 Alternative missions (Alternative meaning they take place on the Tanker, Big Shell, and Arsenal Gear) for a total of 511 missions.

8)Snake Tales: 5 separate stories to play through all involving Solid Snake. Three of these Tales have possible alternate ending scenarios. Stories are text based.

9)There are 3 extra Snake's to play as in the VR/Alternative/Snake Tales (Pliskin, Tuxedo Snake, MGS1 Snake)

10)There is 1 extra Raiden to play as in the VR and Alternative Missions: Raiden in the Gray Fox Cyborg Ninja outfit (he uses only the HF blade which provides hours of hack and slash action)
*note: I won't even mention that one tiny little VR Mission with "X Raiden" aka naked Raiden.

11)GameShark / Action Replay codes will be available which will allow even more gameplay possibilities.

WHAT PS2 SUBSTANCE HAS THAT XBOX DIDN'T:
(ALL NEW FOR PS2)

Skateboarding: With Snake and Raiden.

Five extra characters in Casting Theater: Cyborg Ninja, Raiden (ninja), Otacon, Meryl and Substance MGS1 Snake

Two extra boss battles in Boss Survival: (1) a battle against the Arsenal Tengus where you probably control who you want to (Snake or Raiden) while the other provides back-up, and (2) the tanker soldiers shoot out battle.

If you have a save file on your Memory Card from "The Document of MGS2" it "may" unlock every character and stage in all of the VR/Alternative Missions at the initial start of the game *(I will confirm this as true or false on 3/5)

"The Document of MGS2" is exclusive to PS2, so it's possible the save file deal could work for the USA PS2 Substance (a possible extra reason to own Document)

There won't be any slowdown in frames per second like the Xbox version had (Aft Deck of Tanker):
