Where can I get my machine gun from death island? How can I go out?

Q:How can I go out of the sewer (the one with an organic gun)? Is it true that the original road is returned, and the road is not returned if it is bypassed after the sewer?

A:Keep walking, try your luck, hit the east and west, hit an empty place, and there was a rifle in the hand above the cab. Quickly eliminate botnets on the console

That level has nothing to do with the plot. When I got the assault rifle, I continued. When I got to the bottom Submarine Room, the water began to flow and all the zombies were killed before the water arrived at the platform. In the past, you will appear at the entrance of this underground tunnel.

There was an exit in the room where the machine gun was taken. It looked a little like it when I followed up.
