Hi can any one help me make a map or tell me how and waht i need
You need the lastest version (full) of the SDK (software development kit)... radiant is the program needed to create maps!
Telling you how to make a map is impossible... it is way to complicated to tell you that in a few lines!
I suggest you start reading some tutorials, like these: http://www.gdconnect.com/modules.php?op=modload&name=SOF2Mapping&file=preface
GDConnect has also tutorials for SOF1... i suggest you read those as well (many things are the same, especially the basics)!
