The Tunnels - For Cave People and Molerats

The Tunnels

Hey you! Get lost!

In a network of tunnels stretching from the Glowing Sea to the eastern coast

Some were created due to erosion, some were caused by molerats.

Or  maybe it was one of those exploding mirelurks.

A dozen entrances are scattered around the western and northern commonwealth.

Some can be accessed easily, some are hidden in plain sight.

A huge amount of tunnels and caves with a unique variation of fauna and flora.

Each tunnel segment has a unique theme so navigation gets a bit easier.

Of course you might stumble upon old cellars and whatnot.

The more closer you get to the glowing sea the more dangerous it gets

Damp Caverns

Flora and Fauna

A lot of flora is passive. Some spits out gas or just lightens the surrounding areas.

Some you can harvest. Don't worry as they glow most of the times.

Blastberry: Makes a good grenade. Rarely explodes when being picked up

Cave Flower: Reduces your health. But reduces your rads way more

Energetic Mushroom: Gives you extreme energy resistance for a short time

Really unnoticeable Mushroom: It's the dullest thing really.

Water Rose: You can breathe underwater for some time

The fauna constist of unique variations along with one new type of animal.

Some special enemies do explode or give you metals they have eaten.

Other items let you shoot lightning or make you unnoticeable to Mirelurks.

Well you can find out yourself.

Further Infos

Most of them have map markers outside.

All of them are connected. But one connection is one-way only.

There are primitive player homes but no workshops.

You can take companions with you but due to the uneven terrain

they will have problems following you all the time

Some sections will be confusing but for the most part there are no significant dead ends.

There is stuff to discover. But this is not a huge lore or quest addition.
