Whats the player command?
 

I forgot the command to set the players to 8 or 16 to increase the amount of experience you receive per kill... anyone?

is that were you type in "player 8" or so i think but am prolly wrong

i thought i also heard it was only on single player

yeah it if for single player only you have to type /players x where x is the number of players for the increased xp and harder monsters only works up to 8 tho

yes, it's single only.

well i have tried it on b-net and it seemed to work cause i couldnt kill as easily as i could before i typed it in but either way you can try what i did first type "players 8" and then in a new message box type "player 8" without the quotes of course

SINGLE PLAYER ONLY, type /players 8, such as /fps, etc.
