Invisible Monsters is a texture pack that makes every dangerous mob invisible(save for wolves)
This pack changes the meaning of hardcore as you are being attacked by invisible creatures.
With invisible monsters everything that once was easy will now be difficult. Your only way of orientation for monsters is the sound you are hearing or maybe the armor they are wearing. This texture pack is not for those with a weak heart as the night will become terrifying.
Enjoy the new minecraft, enjoy your fear, enjoy Invisible monsters.
WARNING: Creepers are even more annoying than before!
