So i got final sun to work (Big thanks to those who helped me.) And i tried making a map. It started off as a testing ground, a small 50x50, but then it started to shape well, so i continued. I only spent an hour on this.
A mutant base

Part of the city

An evac point

STORY:
There was a city in America that was a very safe place to live. It was very unexpected when a meteorite hit the city, causing catastrophic effects. GDI tried to harvest the tiberium, but there was just too much. Evac procitures were made. As the civilians moved out, the mutants moved in. It is now a very valuable harvesting ground.
WARNING:
At the beginning, you get very little building space. You will need to expand into the city and maybe into the mutant base. Fighting will be intence, so i advice playing on tech level 8, or round about there.
Remember. I can't light maps, or do triggers. It's my first map... ect.
Someone tell me how to upload it please. I can't upload this type of file.
