All hard work has been done for you. This download includes step by step instructions on how to harvest the data from the Xbox live version of marathon 2. But not only that. It also includes an altered shapes file and new MML scripts to make everything work.
It's no plug and play. Harvesting the textures takes some effort on your part. Expect an hour or two if you're not familiar with python programming.
When all is said and done. You'll be a little proud, and very thankful to the authors for providing you with this excellent download.
These files will allow you to extract and implement all HD sprites and textures from the XBox Live Arcade version of Marathon:Durandal into your AlephOne installation of Marathon 2.
Detailed instructions on how to get it working can be found in the included ReadMe file.
This was made possible thanks to the combined efforts of Treellama and thedoctor45.
Hope you enjoy.
