Jurrassic Park: Chaos Island

[The Levitating Nun]

Not operation genesis which was released in the last few years but a different one released in which you controlled the characters from the films and could hatch dino eggs to help you fight off hunters. It would be really cool to see it on the site if anyone's got it.

I remember playing a demo of this a while ago. It was quite fun, don't remember the name of it though.

EDIT: It might be "The Lost World", not sure though.

[The Fifth Horseman]

Jurrassic Park: Chaos Island, IIRC. Read a review of it once, years ago.
