um ok, i have made a map where there a a huge g4cube in the middle, on the sides (not the g4 further away) there are 4 mini g4cubes. The mini g4 cubes are hollewed out and i can c through them already (if i go in them) but i still cant shoot out of them.
my second option i guess would to make a little passable window, people could still shoot in but i guess the people inside the cube could duck away!?
