TotalDead

Improves vanilla zombies, husks, etc. Now they don't burn in the sun or fire (only in lava), walk much faster, deal more damage and have much more health (for example, you need to hit them 5 times with a netherite sword with a critical hit)
Also the mod adds two new zombies (I hope I will add many more new zombies).

The first one is a brain injured zombie. As you already understood from the name, its brain is damaged, and you can see it on its texture. Because of this, it moves much slower than vanilla zombies and deals less damage, so you can just walk away from it. It also drops a new item - a infected brain. It is not used in any recipe and is basically useless, but if you eat it, the consequences will not be pleasant.

The second one is a shrieker zombie. It is blind, and it senses your presence only if you get too close to it. He is so weak that he can be killed with one hit even with a bare hand, but when he dies, he screams and summons a small horde of zombies (5 to be exact).

I am trying to add more content, so it will be better if you will read changelogs
