its perfect a subway a street full of zombies LOVE IT
Thank and +Rep

Where do you mean in Eviction?

the mystery box can be seen in a few maps. its a template, that was used for mp. remember zombies was done in spare time, so they used pre existing templates. htis does not say anything about the location of an mp4.

But it might be because it suits it
a roof with a bridge a place to jump down
even a little place to make a starting room
