I found some problems with the xml's/data for the space marines that prevented them from running on linux, one was something minor in the smoke xml for the factory, where it had three punctuation marks rather then two and the second was that the .wav file for lasers was capitalized, making it not work on linux. here's the fixed up xml's for linux users, It already runs fine for windows and isn't changed from Mr Wars faction, just some troubleshooting, thanks

Edit: Oh, and Ishmaru can I borrow your Alliance IFV or Tank model for my faction, I decided to add some captured piece of equipment that the Mordavian's use for infiltration and though this will have little in game effect, I feel it would come as a cool perk

Heres several pictures of my Spider RCL, it comes out of the barracks and packs a serious, if underarmored, punch. Though poorly armored, it can deploy for greater ROF and armor from the increased stability. Its cannon is pretty good against enemy vehicles and buildings, but its armor is worse then an IFV's, meaning that it rolls in, fires its 123mm RCL and pulls out of range, or it helps augment the early game defenses, which only consist of MG bunkers, as this faction lacks any form of rocket or dedicated AT bunkers, but rather entrenched unit forms and a late game tank turret.
A last question for Ishmaru. As your not using the MG bunker any more for the Alliance faction, I wanted to ask, can I use it for the Mordavian faction, I always felt it would suit their faction well and this saves me the time of makign a pillbox, though I might edit some things on it.
