An excellent companion to the "Marathon Durandal Textures @ 1024X1024" plugin since that plugin doesn't have built in landscapes. Note: these textures are not "HD remakes" (they do not match the originals in any way) but still fit the environment very well and are of higher quality than Freeverses' landscapes.
Plugin Version of Tim Vogels 'High-res Landscapes v1.1' for Marathon 2 Durandle.
