An updated version of the modpack seen in "I Survived 100 Days in Hardcore Minecraft with Parasites by Forge Labs!" combined with Modern Ruins Pack gives you the feel and experience without the original Forge pre-generated world.

You spawn into a world that has long since witnessed a biological apocalypse, your mission is to explore to see if it has all died out, however in between the hoards of zombies, you see they were just dormant...they just needed a familiar host to wake them up again....you

The world which seems abandoned and overgrown has somehow become re-infected with a parasite, and it's spreading quickly. You are stuck, your recall device just keeps you respawning in the same place, it's time to make a stand, or give in to the taunting voices in the back of your head,...wait I'm I infected too? 

-The main mod featured in this pack is "Scape and Run: Parasites"  
-Modern Ruins Pack adds a bunch of random ruins to give the appeal of the famous Run through by Forge Labs but with any world-generated map.

-Just Another Rotten Flesh to Leather Mod is added to fill the issue where cows are no longer leather sources.

-Gliby's Voice Chat Reloaded is loaded, It will require a little configuration, but i felt it is important to have your buddies hear you scream or vice vera

-Xaero's Minimap is good to know where you died at...however, the real trick is what's wearing your skin and how you plan on getting your stuff back...well good luck.
