TFWR

The Few Who Remain is a Hardcore post apocalyptic modpack set in the future. This mod is intended to be at least a bit challenging, as you will have to deal with hordes of zombies, hunger, thirst, temperature, and worst of all the Parasites. At first you will crawl out of your bunker and deal with the hordes of zombies, but soon enough those will be hordes of Parasites. Currently the modpack is in Beta, and there will be updates every once in a while.

Tips:

Get lava as soon as possible as the nights are extremely cold (this extreme cold is intentional, however I may make adjust this in the future)
Every eight or so nights there will (or should) be a zombie horde
If you see a block that looks like a tape recorder seemingly in the open, dig beneath it and you will find a bunker full of goodies
Always remember to bring a flashlight with you, and do not panic if the bunker you spawn in is practically pitch black, just flip on the lever or turn on your flashlight

When creating a world you have two options to choose from:

The Wasteland

The Wasteland is the result of non stop nuclear war against the Parasitic Invaders. There are a few structures that survived, however it is unknown if some were built shortly after the Earth became a Wasteland, or before it became one.

The Lost Cities

The Lost Cities are the result of some warfare against the Parasites, however not nuclear war too the scale it was in the wasteland.
