Making A Zombie Map

Hello Halo fans, I have recently embarked on creating a zombie map in H2A after seeing a video posted by MartianMallCop (https://www.youtube.com/watch?v=_iJiFXHsD0Y) where he made a functioning random box. I have almost completed my original design but I feel that it is missing something and would like some help/feedback.

If you are interested send me a friend request and message on XBL, GT RAZzBIHiddnFall.

Thanks.
