In Minecraft Classic, four iconic mobs were added to the game; zombies, skeletons, spiders, and creepers.

Since then, sprinting was added, enchantments were added, and shields were added...

It is now incredibly easy to survive an encounter with any of the original hostile mobs. All you have to do is run, block, or fight back with enchanted weapons.

"Surviving the first night" let's play videos are a thing of the past, because there's no tension anymore.

Creepers lost their meme status as house stealers and grim reapers, because they can't chase you if you run 16 blocks away, and they no longer strafe when they hiss.

And no one is afraid of the dark anymore...

Changes:

• All classic mobs are faster. It is equally as hard to run from them WITH sprinting, as it was to walk away from them in old Minecraft (which didn't have sprinting).
• All classic mobs can see farther. Mobs will chase you farther and it is harder to get away.
• Zombies: 35 -> 40
• Creepers: 16 -> 24
• Skeletons: 16 -> 32
• Increased the follow range of skeletons and creepers
• All classic mobs are sped up just enough that it is equally as hard to run from them WITH sprinting, as it was to run from them in old Minecraft (which didn't have sprinting).
• ALL zombie variants (except for babies) have increased melee damage to match how much they had in beta (melee damage was nerfed in modern Minecraft).
  • Endermen do more knockback and are more resistant to it
  • Ghasts are common like they used to be.
