This was a 3-level set that I worked on over the course of a few years during the mid 2010s. It was inspired by Palmyra in Syria, legends of the Djinn, and the concept of finding a hidden paradise deep in the desert. It was to feature three levels: The first saw Lara braving a Sandstorm in the jeep on her way to the Palmyra site, then she would find a way underground in Palmyra to the next level. The next level was a cavern of Djinn, with strange magic and Djinns haunting Lara. Finally she would break through to an Eden-like paradise in the third level, which had a hanging gardens vibe.
I’ve adapted some of the Djinn aesthetics and custom textures into my upcoming remaster of Lara Croft and the Forty Thieves, so most likely these ideas are going to live on there and this project won’t progress any further.
