What's PvP?

PvP in Minecraft results in the death or injury of one or more players. When a player dies in normal difficulty, the contents of their inventory are scattered on the ground. This creates a powerful incentive for players to participate in PvP, as successfully killing another player rewards the killer with the dropped items, and sometimes reputation and power too.
