Underground Jerkway
The Underground Jerkway is a relatively obscure area. Many players will go through the game and never even notice it.
Location
The Underground Jerkway is located underneath the church in Lurleen.
Attractions
There aren't too many reasons to come to the Underground Jerkway, but it is a fairly good location for lower level players to grind. There is also a shop known as the Hollow located in the middle area of the Jerkway.
The Jerkway also connects Lurleen to the Freedom City sewers. There is a relatively simple climb up a well that leads to a zombie infested field. Too bad the zombies are passive and cannot be attacked.
Denizens
The enemies located in the Jerkway are relatively easy. They can be compared to kittens in Crater Rim.
If you are going to grind in the Jerkway, be prepared to fight spiders. The cave spiders here are much easier than the ones located in the mines. They are still spiders though, so be careful not to be poisoned by a spider bite.
