Some nifty little surprises that don't require you to do anything in-game prior. All you need is a completed file of Silent Hill 2 on the same memory card you're using for your Silent Hill 3 play-through.

The references are as follows:

In one of the bathrooms in the Mall, if you examine a toilet, it will ask if you'd like to investigate it, and it will play a little cut-scene. Heather will go and reach for the toilet, but will then stop and note how disgusting it is. Then, she will look at the camera and will say: "Who would even think of doing something so gross?" James Sunderland, that's who.

Once returning to the Daisy Villa Apartments, look in the mailboxes, Heather will make note of a letter from a certain someone.

While Douglas is driving Heather to Silent Hill, he makes note that he was on a missing persons case a few years back. Who do we know that's been to Silent Hill since Harry discovered it's horrible secrets?

In Heaven's Night, there will be a poster saying: "Lady Maria has returned!" In the sub-scenario of Silent Hill 2, Maria starts out in Heaven's Night. Although the girl on the poster has black hair, game developers say that Maria had dyed her hair.

On the roof of Brookhaven Hospital, examine the fence. Heather will make note that it's rather sturdy. Yeah, after Pyramid Head knocked James off he went and fixed it.
