The CrackedZombie Mod beefs up the threat of Zombies in Minecraft to a terrifying degree. This mod removes the default Zombies and instead adds a new breed that walk around during the day and in groups.
This mod makes zombies more of a threat and something you definitely want to keep a closer eye on. They will now attack livestock so your resources are at risk too.
What makes this mod so cool is it gives the player a post-apocalyptic feel to the game. You are now surviving in a much more difficult environment. Daytime is no longer safe and the threats of attack have multiplied. If you’re a die-hard survivalist, this mod may amp up your experience. It’s perfect for lone adventuring or surviving in groups as you would in a real zombie apocalypse. It’s a very simple mod with dire consequences.
There are also options to control the spawning of other mobs so you can limit what enemies you’re left to contend with.
