Removed normal because it caused some trouble, this problem didn't arise when I play it with the non-pakage map file with the custom file in L4D2 directory

Hotfix3

hotfix 2

Hotfix

Added grenade launcher, chrome shotgun, made the sourinding wall on upper floor solid, made the climbable pipe model not solid, and flag pole is now at the correct position.

Custom texture packed into .bsp using VIDE.exe, hopefully this would fix the missing texture black and purple checkers issue.

Various fix, again

Readded Tattered Vietnamese flag(It won't replace the default American flag)

Added normal map on custom texture

Added tattered Vietnam flag texture.
