Pretty much i was messing around with photo shop and was playing with textures. Then suddenly, BOOM i had a map. A few notes is that i found a wierd method of construction that i never knew about before, and it makes texturing easier.
There are actually 4 bomb locations, each spread throughout the large dynamo by the ct spawn. pretty much plant the bomb anywhere in that room and watch the ct's scramble around looking for it. The T spawn area looks like a miniature AIM_MAP to me... but whatever.
