Yello!
Firstly, EXCELLENT job at re-imagining the map. We'd have never thought of some of the ideas you put into it. The warthog not being in the bottom of the base is kinda cool. Its like a mini-puzzle to get it out.
However, I do have some criticisms and questions.
Edit: Sorry, didnt catch the first part =/. You used teleporters n boxes n stuff. Good boy.
I see tons of campability factors when it comes to your custom powerup bridge. Unless the Zombies can simply jump up there, you're going to have a LOT of campers on your hands.
You NEED to somehow encorporate or completely block up the bottom part of your home base or you're going to have a lot of unhappy people. I know you dont like it, but you're GOING to have idiots that open the base for the lulz, or because they have no idea you're not supposed to. Leaving honor rules in a map is a big no-no. Fix this before you fix anything else.
While the overall functionality of the map looks good, and it looks playable, it also LOOKS sloppy. Believe me, I've built functional maps that look like crap, and defended this. But you need to put time into making your map look as clean as possible. Interlocking and Geomerging helps out a lot. I know the I am Legend maps are naturally cluttered, but there is always an order to chaos. I can't tell you HOW, but you do need to clean the map up a bit.
The "Pyramid of Bang"?...Naw...
Frankly this just discredits you and your map. Its a common early map makers mistake to make something kinda stupid and wierd in thier maps. Trust me, if it doesnt serve a specific purpose, take it out. (Unless we're talking about asthetics)
I know thats a lot of negative to take in, but thats how you get better. But again I say that you did a VERY good job on this. Making an I am Legend game work is a tough task in and of itself, and it looks like you're very close to having yourself an excellent map.
Thank you for all the credits as well, Y4ZT would have totally blown a gasket had you not =D.
Also, here be a link to the original Nightfall and I am Legend gametype:
