Jurassic Park: Trespasser was aimed to be a massive open-world survival game, released as a digital sequel to The Lost World. Sadly, this didn't turn out too well because so many locations and features had to be cut due to hardware limitations and time constraints during development.
Years after the game was released, a few prototypes got dumped and they're a lot different from the final game. There are a lot of noticeable differences, details, and even minor level changes! As time moved on, more prototypes were released and some former developers of the game even contributed to the mysteries that surrounded the game's development and original presentation.
