Aside from simplification of level geometry, the main significant change compared to the PC version is to the donut-shaped walkway. In the PC version, the walkway is surrounded by a deep, inescapable nukage pit, and has a "hole" in the centre which can be raised and made non-damaging with a switch. In the console version, the walkway is surrounded by a very shallow nukage pool, and the "hole" is not present.
