A total of 61, 256 x 256 (pixels) high-quality textures for use in any type of scenario.

This archive is packed the MML script when using a Japanese Map by AlephOne, and the resource which puts application of AlephOne into Japanese.

Many things of Marathon have been improved since Aleph One came out: OpenGL graphics, high-res textures, and even a couple of 3D models are made. But there's one thing that has never been improved...Sound.

This is probably because the sounds in Marathon are still quite good, but we found ways to make it even better.
