Scratchbuilt Marathon 3D Game Thread

In 1994, an upstarter computer game company called Bungie released a pioneering first person shooter that would have a profound effect on the genre for the Macintosh. It’s cerebral plot line and simple yet immersive story captivated a whole generation of gamers with its mix of existential philosophy, poetic narration and ultra violence. Today, all but forgotten save for by a shrinking group of loyal fans and ageing Mac users, reminiscing with teary eyes about the old days of MARATHON.

Once I had first stumbled down the winding hallways of Hangar 7A, I knew I was forever caught in its gloomy death stalked corridors; the horror, savagery and despair of my battles with the Pfhor forever tattooed on my retinas.
I never thought of escape.

To this legacy, I want to pay my homage. To give thanks for the experiences which no doubt altered my outlook on life irreversibly and moved me deeply.
To this end, I have toiled for months to bring Marathon to life in a whole new setting.
But I cannot do it alone.

What I am trying to do is to make a cross platform team based Marathon online experience, where players act out the parts of one of the three major species of the series; the humans, the Pfhor and the S’pht.
I am getting closer all the time. However, I am impeded by the fact that I must do everything myself and I have little or no training in doing so. Only my loyal love of Marathon drives me to overcome the problems.
What I need help with the most is 3D modelling. Particularly levels. There are a number of high definition Marathon textures available to model with.
Any help gladly appreciated.

See you starside.
