A concept idea I had from an old let's play on YouTube back in the day.

The concept was, zombies agro from afar and are able to break almost all blocks.

Just to make the Minecraft experience a bit more spicy since mobs aren't really that much of a threat in Vanilla Minecraft.

Some mods may not be on the latest version, update at your own risk!

Updating these mods on your own may cause the config files to become broken.

Things added in 0.7.728 are:

Some minor bug fixes with Zombies not wanting to break blocks.

Adding a few extra mods to make the zombies spawn more frequently and to make early game a bit harder.

Things changed in 0.8.730 are:

Removed DamageIndicators and Ruins Mod because of instability and crashes (not the mods fault, just my incompetence).

Changed a few config settings because of random crashes when loading new or already made worlds

Added custom sounds and self made textures to the game with a resource pack

Changed some vanilla recipes to make survival even more difficult
