Rama's environments are designed consistently to the descriptions of the books. Rama is a huge, featureless cylinder of 50 km length and 20 km height. Rama's length is spanned by 3 huge beams that produce light and create an artificial day-night cycle. The game begins at night but becomes day soon after.
Rama is divided in 'Northern' and 'Southern' hemicylinders, divided by the Cylindrical Sea which during 'winter' is frozen.
An arrow in the lower part of the interface, points towards the Raman 'north', which is the opposite end of the cylinder, so that the player has a better orientation while exploring.
The 'entrance', where the ISA installs the Hub with supplies, lockers and living quarters, is the southern 'pole' which contains the airlock and climate controls. The game starts there. Built in the centre of the cylinder's rotation according to the book, the Hub should have no gravity, but in the game this details is neglected, because navigation would be awkward without gravity.
The South is occupied by the Plains that feature hills and cities, named after Earth places. In the game, the player will visit several places, but of the cities, only Bangkok (actually a museum for each of the species) and London. The player travels in the Plains by the means of a map, projected by his wrist communication device.
The Plains are connected to the Cylindrical Sea which in the game, is seen frozen. The Sea is occupied by a huge island of enormous structures, for that reason named New York. There, there are three 'plazas' for each of the species, the Avians and Myrmicats, the Octospiders, and the Humans.
The opposite part, which contains the propulsion mechanisms according to the books, is never visited in the game. Cities like Rome, Paris, Moscow mentioned in the books are never brought into consideration.
