Minecraft: The Survivors’ Book of Secrets: An Official Mojang Book

This official Minecraft(TM) book contains the collective knowledge of the Survivors: an underground group of Minecraft(TM) experts who have been around since the days of Alpha.
You’re probably wondering why you’ve never heard of us. It’s because we’re THAT good. We’re experts at covert ops. Misdirection is our middle name. We’re invisible up until the exact moment we want you to see us. . . . Our successes are undeniably impressive: we’ve battled the Overworld mobs, dealt with enemy factions, and defeated the ender dragon multiple times.
Study this book carefully and you just might manage to stay alive as long as we have.
