Have a peek at the two Devouring Darkness announcement threads, and the player guide.

Here’s a few highlights:
- Zombie Awareness: All monsters are omniscient. They know where you are. They ARE coming for you.
- Special AI: Monsters have armor and abilities. There are more varieties of monsters (ie: Ender Creepers which teleport). Finally monsters actively grief player creations. Chests, tilled farmland, glass, lights. Zombies smash them, creepers BLOW THEM UP. Bye bye walls.
- Infernal Mobs: I lowered the spawn rate of mobs, and instead you will often run into mobs with enchantments. Zombies throwing Ghast balls which explode. Slowing, rusting (hurts your armor more), revenge (you kill them, they explode to hurt you). They are mean.
- Blood moons: 30% chance of blood moon, so night time is incredibly dangerous to go out.
And more. Plus I make food and the world balanced. The idea with DD and my packs is that early game you are WEAK. You should run and hide, and be clever to avoid combat. As you tech up, you can become godlike and never worry again about monsters. It’s a slow climb, but accelerates the further you go. Make a safe base, and just worry about GT6.
