The Bosses of Mass Destruction mod adds four new and unique boss mobs to Minecraft, each of them spawning in different locations, with different appearances, attacks, and drops.

Minecraft's Boss Update will add two boss creatures. One is the Wither, a floating, three-headed mob. Defeat it, and it might just drop the ultra-rare nether star item.

Minecraft is one of the biggest games in the $99.6 billion gaming industry, and it is consistently one of the best-selling games on consoles, PC, and mobile devices.
