This project was envisioned when I was playing through the original No One Lives Forever. When I reached the secret Dumas office, I instantly knew this was what I wanted to remake, right after I finished the ArtStation Space Opera challenge.
I gave myself 1 month to finish, which I did achieve and am more than happy with how it turned out, especially with the number of things I learned from the project=)
