This is the first level to a three part trilogy. You start out in my part of the map once you get into the other house you are in the part Nubblecakes did but we take no credit in the outdoor area That part of the map was made by valve....well the brushes anyway but the entities where done by Nubblecakes

So, default is an sandbox singleplayer, hl2 campaign mode.
