I've been toying around with the idea of intergrating sewer systems and storm drain tunnels into night ops as a far more efficient way of traversing the city undetected, granted you have invested in the equipment to travel long distances in the sewer system. (boots, maybe a dingy even, night vision or high powered flashlight...)
I see the sewer system and other underground tunnels as a great escape route from cops as well, a good place to drop a smoke bomb if a cop dares to follow you into one.
For now, I am focusing on a couple storm drain tunnels that go for a couple blocks that could work out as some great escape routes.
Where could you possibly get the scematics of a cities sewers and storm drain tunnels?
Also I am thinking about even getting into some storm drains and those metal things in the middle of the street, can you even fit into these sewer pipes?
a tire iron to open the sewer hatches and your in! if you have insurance and are considering this.
GO GET ALLLLL THE SHOTS YOU CAN
get current on everything and tell your doc you got a job working with sanitation so he knows what to get you!
also if you come across an AIR meter those are a real lifesaver
you could also wander around town lookin for one of the sewer trucks wait til there in the sewer and pilage their truck for the safety equiptment you might need... i bet theres extra air meters in there
