Deathwish Readme

Deathwish focuses highly on finding new books to learn not only some of the basic recipes found in Vanilla but also more complex things added by the mod, like for instance, Polymer Clay or Rubber.

Most of the changes you'll find from the Vanilla game are: Below, the changelog from the Deathwish readme link:
 * Food and water are less filling. This means you'll have to eat and drink more to keep yourself from starving/dehydrating.
 * Wellness increases more slowly.
 * Melee weapons are rebalanced; while early weapons are stronger, vanilla later weapons are slightly weaker, but the higher variety of weapons makes the end-game melee weapons of Deathwish slightly stronger than the Vanilla ones.
 * More zombie types. Some will sprint at you in daylight. Others will crawl up to you and explode, and some are extremely tough to kill, but very slow in all times of day.
 * More books. Deathwish has more than a hundred different books of different rarities. While the most common recipes, like crafting Wood Planks, are easily found even in zombie bodies, books that teach how to craft more powerful guns or chemical components require extensive looting.
 * Medicine now has cooldown on Aspirins. While this greatly reduces stacking aspirin intake for quick health, more variety of health items are present, like painkiller shots of different sorts.
