Sphere or planet? (Dead Space 2)

In General, the mystery to fans of games like what color is the dress. Somewhere in the beginning of the game there is a picture where on some planet there is an island here, it is unclear whether behind him another heavenly body, or the island itself is surrounded by a sphere. Why did I ever think that it could be the scope? Just the fact that EA also has the game Crysis, which is the island of Lingshan, which in the end will be surrounded by a sphere Tsepov, so this may be a reference. What do you think?
