City

The City map is a map that has two buildings, two Machine Guns and a sewer system? Which is where spawn is located. This one of 3 maps that have a jetpack also including Desert and the Moon. In the City and Desert maps, you can get the achievement "Can Into Space." You can't achieve this in the Moon map since the top is blocked of and you are already in space.

Design
City takes place in a town full of buildings in the background.
