The Hunger Games Mode is a game-mode that can be accessed by switching to HG mode on the game menu. It is very similar, gameplay-wise, to the normal game, but the server is only open for the first 10 minutes, and upon death, players get eliminated and must wait for the next round. After 45 minutes has passed in a Hunger Games server, resources and animals will stop spawning (including ground resources), and the bread market is disabled. This is indicated by the message "They are no more resources" appearing on-screen. The objective of the game is to be the only player left. If the server is closed, players can still join, but only as a spectator. There are currently two HG servers: one in North America and one in Europe. An additional Asian server is coming in the near future.
SpectatorsSpectators spawn with the Explorer's Hat. They are, by default, invisible to other players, unless if they have pressed P, which shows spectators. Spectators can be killed by real players, mobs (by moving with them purposefully), and by fires and spikes. Spectators cannot choose their username (it will always be "spectator"), but they can still choose their skin. A spectator's cold, oxygen and thirst bar will never decrease, but their hunger bar does (consider it your time limit). Spectators can't hit anything, so they can't gather materials, damage structures or mobs. They can also pass through resource nodes and structures.
Hunger games will continue indefinitely until one person remains.
