here are some starter saves for Hardcore & Pure survivalist at the 1st work bench on chapter 3 with the devil horn's equipped and the 1st levels are at 100%.
also the saves now have max resources.
these are the DLC that i had when making the saves:
Tau Volantis Survival Kit
Bot Capacity Upgrade
EG-900 SMG
hardcore w-devil horn's at start of level 3.rar
Pure Survival w-devil horn's at start of level 3.rar
if you have the dlc and want to play it on hardcore or pure survivalist just load the dlc from either of the saves and you will have the devil horn's and max resources for that difficulty setting in the dlc also.
for the dlc there is no need to clear your cache or play offline if you are using either of the saves.
