Vortiville is the first level (in the official numbering) in Keen 3. It is an optional level, located in the Vortiville Island, in the Lower Vortiville area. It is near Teleporter 1, which leads to the second area in the island, the Upper Vortiville area. However, it is not necessary to finish this level to get to the teleporter.
Though this level is called "Vortiville", it is likely that Vortiville comprises all the levels in Vortiville Island, and this level is just an isolated part of the whole Vortiville.
The level consists of some outskirts with a little hill, a waterfall and a cliff, and the Vorticon's house. The first building of the house has three floors: the first one has a living room and a kitchen; the second one, a dining room; and the third one, a bedroom, apparently the kids' room, as it has a lot of chocolate and a toy. The second building has two floors: the first one has a garage with an air-car, and the second floor appears to be some kind of workplace.
The Vorticons in this level appear to form a family: there is a Vorticon Woman, three Youths, and two Vorticon Grunts; one of them is probably the father, and the other is either the uncle or oldest brother, who lives in the garage.
