Weezer Sewers
The Weezer Sewers are sewers that are, naturally enough, located beneath Weezer. Like the Freedom City sewers, there are a few things to be found here, and walking around will naturally get you covered in unmentionable fluids.
The only mob that spawns down here normally are the rejected clones, clones that were cast aside for their mental deformities and now call the sewers their home. They are very weak, with combat skills equivalent to regular FC citizens (that is to say none at all).
When a Ripperscrub Invasion Contract is signed several Ripperscrubs can also spawn down here.
There is also Chet, the guard of the Brainslug larva, who is hidden in secret place that you have to search around for. Chet is a real motherfucker, and will fuck you up if you don't come prepared to kick some ass.
