i?ve downloaded EP.1 in the time it was released, but as i apreciate valve?s work i?ll buy the orange box, as soon as it arrivesa here at the stores in Brazil. so i was trying some mods to pass the time, waiting for it to arrive. how can i make a map that requires EP1 ? i tought it would need the source SDK BASE, not the Episode. so if i wanna make a map with depth of field i must have EP2 and the player too, as depth of field was introduced in the EP2 ? am i right ?
