I forgot to tell you a thing last time: Both armory spots are levitating in the air in each base, they look weird, I suggest you put them at the correct height.
And second, I bring you a suggestion:
Put those metal cubes into the metal objects group. ( The thing is in all points, just select them all and drag them into that.)
So that when we are walking on them, it will make a metal platform walking sound, also, when bullets hit them, it won't be created any bullets hole but a metal hitting effect.
