alright here's my feedback:
overall this mod has a strong strategical meaning, i like the name of "holding the line." however, there's a few things to be improved upon. of course this is only a first beta
first off, the file size is 304 megabytes, that seems wayyyy to large. did you copy the entire rep / cis assets? you only need the ones you used.
anyways, when i spawned at the default rep cp i noticed a glitch in the bunker. to the right you have a minor glitch easily fixed up with some terrain work. as i moved on i noticed the bunkers had no texture, just a black illusion. im not sure what went wrong there, you might have textured wrong. also, the top right command post is doubled up, so when i captured it there was a blue and red light shining. i suggest deleting or moving one. so aside from the occasional droideka-stuck-in-a-terrain, nothing else was fundamentally wrong.
now on a gameplay viewpoint, there are a couple improvements needed to be done. the map size is very small, perhaps you wanted it that way? if so, try to fit the title so the command posts are distributed that way, it didnt seem like there was any tactical placement.
the terrain is nicely painted, or formed, whatever lol. all you need to do is smoothen it out so it seems more natural and fluent.
command posts, again, are a bit too close and dont seem to take on an importance. placing command posts next to crashed ships and whatnot make it more strategic and meaningful.
also, creating more obstacles and lower spires could make use for a good sniper or jet trooper. finding a nice hiding place to kill off enemies is a plus for the player. example: top hill on the original geonosis.
lastly, original skinning is always welcome and makes the mod feel even better. if you can skin, id recommend it.
so yeah, thanks for letting me beta. with those improvements / suggestions this definitely would be a great mod.
