Level 12: Bob's Big Date
This is a large and complicated level. With the ebb and flow of sewage there's a degree of difficulty involved when trying to get to the various rooms.
At this map location there's a 3x re-charger which will come in very handy.
The exit terminal is located in the middle of the level. To get to it you have to jump from one of the outlying rooms. A hint? Look at the map.
To exit the level just read this terminal. But beware, it is heavily guarded.
