Another box map exactly identical to every other box map on UGX. I'm not usually so hard on box maps but it's getting to the point where every other post is a low quality post for a quick 12 people to play it. It's boring, dull and makes for an experience that I'd rather just quit on round 4 than to play through.
I've absolutely no idea how you managed to hit the 400 fx limit without even adding anything custom. The radio was about the only thing that was unique to this map. Please, take some time with radiant and learn about it. Take some time and put some creativity into a map rather than making a barebones functional zombie-box and calling it a day.
This may be your first map, but that doesn't mean you have to release it. Look at other examples of decent/UGX maps and take from them, don't just post things like this, because it's just spam.
As klevi said, if you need help ask around or add me Numan#4274.
