The graphics are stunning yes
How the author has you implement them is not, assuming you have an xbox360(or even want one) and going through a series of complicated steps to put in the new shapes

A terrible waste of time
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.
