The “Original Version” of the Hammond Memoir, created back in 2007. The way it was mixed and edited resulted in a much inferior product than the later versions. It also doesn’t include any of the recorded dialogue from the beta version of the game, because it had not been discovered yet. But for some, this is still the classic version of the audio memoir.
The audio program includes cover art (featuring the original logo), an alternate cover, two sets of special CD covers by Roy Govier, a tracklist file, and a PDF text-only book version made by Zoltán Jenkei (aka “Hundolos”).
The videos above were also made by Zoltán (excl. “Hammond’s Diskette”, which was created by Derrick Davis). They have since all been replaced by the Definitive Edition’s video program, but they are still a joy to see with creative use of Trespasser’s locations.
NOTE: Some later editions had video versions made as well, but they were largely just a series of still images without any effects. None of these older videos will be archived.
Back in 2010, “Version 2.0” of the Hammond Memoir was created to present a better mixed and modified experience of the “Original Version.” However, the biggest reason for its creation was to include dialogue that was discovered in the beta version of the game; the remaining missing recorded dialogue from Hammond. While most of the music was still from inferior sources, this version of the memoir was still a great upgrade from the original.
The audio program includes cover art, an alternate cover, a tracklist file, and a text-only PDF book; made once again by Zoltán Jenkei.
The “Annotated Edition” of the Hammond Memoir was a unique experience that expands the story of John Hammond. Created in 2013, it uses the complete audio from the game interwoven with a new character created just for this edition: Thomas Hammond (performed by Jack Anthony Ewins). The character’s tracks explain more of the story, in his words and readings, based on the original script. During these tracks are original music by Derrick Davis, arranged and performed by Bernard A. Kyer.
Mixing the genius original story with a dose of fan-creation, this is a very unique edition. At the same time, additional sound effects were mixed into John Hammond’s tracks to enhance them; often times taking center stage. This new inclusion was especially appreciated by people who heard it.
The audio program includes cover art and a detailed credits booklet.
When the “Annotated Edition” was released in 2013, it was originally paired with an “Excavated Edition” that only featured the John Hammond-narrated tracks and none of the fan-narrated Thomas Hammond ones. However, after a mere two days, this separate edition was removed due to some confusion from people that it contained unique tracks when it didn’t. However, the “Excavated” title would still carry over into the PDF book that was created alongside it.
The original 2013 edition of the “Excavated Book” used the original script by Austin Grossman and arranged it into a storytelling narrative, much like the audio programs. Given the script had so much more information, it was the most complete experience of Hammond’s tale.
Unlike the final version, this 80 page book was enhanced with exclusive photographs edited from the game ‘Trespasser’ itself. It was made to look more like a scrapbook in tone.
The download includes the PDF book and the original “Excavated” cover file from the unused audio program.
In 2015, I began to have second thoughts on the “Annotated Edition.” While Jack, Bernard, and I put much work and effort into that version, I began to feel it was flawed on a conceptual level and that it was too much “fan-creation insertion.” 2015 also delivered the first new ‘Jurassic Park’ film in 14 years: ‘Jurassic World.’ So, to celebrate the occasion, and to reverse what I had done before, a new version of the Hammond Memoir was assembled.
Instead of making an entirely new edition, 2015’s “Gold Edition” removes the fan-created Thomas Hammond tracks and simply focuses on its version of the John Hammond ones. This was essentially the jettisoned “Excavated” audio edition. However, a pair of new tracks came in the form of an opening and closing designed to make the listener believe the story is told through an old cassette tape.

2017 was a special year: the 10th anniversary of the “Original Version” of the Hammond Memoir. Hence, to celebrate, this edition was dubbed the “Anniversary Edition.” It wasn’t made merely to capitalize on the event. Thanks to the discovery of a source that contained Attenborough’s recordings, without its misty “echo memory effects” that plagued the original and beta game files, we were able to hear the performance clearly for the very first time.
It was important to me to create a new version all over again, from the ground up, in order to preserve the best quality of his performance in the same entertaining way. Due to wanting to focus only on the voice, no additional sound effects were included except in two brief moments and the ones mixed in by the game designers. Newly-created bonus tracks were also included to open and close the presentation.
Unlike the other previous editions, which used degraded sources for the most part, the “Anniversary Edition” was made with mostly high definition or high quality sources. If you want less sound effects and more focus on the voice, this is the version for you. This was meant to be my final edition of the memoir.
In 2018, this edition did have a single track updated, “Hammond’s Diskette.” Content was extracted from yet another ‘Jurassic Park’ related game that also featured Attenborough as Hammond: ‘Chaos Island.’ The additional dialogue included details about more dinosaurs not mentioned in ‘Trespasser’ that was deemed noteworthy in this track’s collection of other odds and ends.
The audio program includes cover art and a detailed credits booklet.
2018 didn’t just have a minor audio update for the “Anniversary Edition”: the “Excavated” book received a complete overhaul. Most of the scrapbook aspect of the original was removed, replaced with illustrations by Felipe Humboldt. This “Anniversary” version of the book became the basis of the upcoming “Definitive Edition” with key differences; such as alternate faux-old paper, a variant illustration of Hammond, and other details.

Over time, people were a little disappointed in the “Anniversary Edition” due to the lack of sound effects that had been included in the “Annotated” & “Gold” editions. Despite the upgrade in Hammond’s voice (the most important part), some felt slighted as if it had regressed. Time and priorities were not focused on undertaking the time-consuming task of implementing sound effects yet again, so I didn’t ever see myself giving in to these desires.
But then, the quarantine of the 2020 pandemic happened. Suddenly there was time to revisit the “Anniversary Edition.” Sound effects soon populated most of the tracks, like before. Additional tracks were also adjusted and created. Some contain additional dialogue from the films themselves. The “Excavated” book also received an update with different faux-paper and additional illustrations & imagery. The “Definitive Edition” was finally finished. Or so I thought.
In 2021, a rare opportunity arose. There was now a way to bring the unrecorded Hammond dialogue from the original script to life with a synthetic recreation of Richard Attenborough’s voice, using audio from ‘Trespasser’ as the source. While I no longer condone the use of a synthetic voice, I have chosen to keep the tracks due to the framing device that was chosen.
The new Hammond dialogue is bookended with the character “Anne” from the game, performed by Minnie Driver: a woman stranded on Isla Sorna after an unfortunate vacation accident. In the program, she comes across “Hammond’s Lost Diary,” which features the rest of Hammond’s intended story with these recreated files. At the same time, the “Excavated” book also received a final update to reflect these new tracks and other final touches.
I made it very clear these new tracks were synthetic and purposefully separated them from the main program’s real dialogue. It was the final step in having the entire story performed in what I believed was a suitable way compared to the “Annotated Edition.”
Finally, the Hammond Memoir’s “Definitive Edition” is complete. It has been through many variations over the years, but this final version will hopefully stand the test of time like the very story it tells.
