The Hunger Games Mode is a starve.io gamemode that can be accessible at the bottom of the server list. It's the same as the normal gamemode, but the server is open for the first 10 minutes --upon die, players get eliminated and must wait for the next round. The object of the game is to be the only player left. If the server is closed, players can still join, but only as a spectator.
Spectators spawn with the Explorer's Hat. They are invisible to other players, unless they have pressed P to show spectators. Spectators can be killed by real players, mobs (by moving with them purposefully), and by fires and spikes. Spectators cannot choose their name (It always be "spectator"). Spectators' cold bar does not decrease, but their hunger bar does (consider it your time limit). Spectators can't hit anything, so they can't gather materials or kill people. They can also pass through resources and buildings.
