18.1.2 Bloodbath

A bloodbath is an arena event similar to a free-for-all. The rules are
simple: Once the event begins, do whatever you can to kill as many
people as you can. Unlike FFAs however, you aren't finished when you
die--you are sent back into the arena good as new to fight again. You 
begin with 100 points, and with each kill, you claim a quarter of your 
victim's points. As always, the last man standing is the victor.

To see how much time is left at any point in the game, type ES <arena>
or EVENTSTATUS <arena>.  If you need to quit early, LEAVE ARENA will
remove you from the game, but be warned, it is irreversible.

Read HELP ARENA for more information on the arena and arena related commands.
