A modified version of Keerdm's Zombie Apocalypse Essentials that is more fit for desert environments, it is incompatible with the former. Pairs well with the Block Swap mod to get rid of the otherwise unremovable grass blocks.

Instructions:

In the lost cities world creation menu, click the customize button and toggle the option that is unlocked to keerdm_zombie_essentials:testworld, then disable rubble as well as leaves and vines in the screens accessed through the top rightmost button. Play around with the other settings as much as you want to get the ideal profile!

I have gotten permission to post this from the original creator, Keerdm, since I just modified the palette, style and highway files, all credit goes to him, go check him out!
