this map is the same as the first version except the custom textures are in the .bsp in this version. last time for some reason they didn't save into the file, so i'm renaming this one "b2" so that nobody runs into problems when they try to play it.
all information about this map can be found
here
download link disabled, pm me if you want the file
EDIT: this version seems to have fps issues, when i get some free time i will look into why its having this problem.
