----  IMPORTANT!
----
----  You should save (press Ctrl+S) this script to:
----  Program Files\Hedgewars\share\hedgewars\Data\Scripts\Multiplayer\Mutant.lua
----     or (on Linux):
----  ~/.hedgewars/Data/Scripts/Multiplayer/Mutant.lua
----
----  (or wherever scripts like Highlander.lua, Racer.lua are on your system)
----
----  Also, if you didn't have Mutant script yet, you need to restart Hedgewars for it to find the script file.
----


----  GAME RULES
----
----  Recommended settings:
----    * one hedgehog per team
----    * 'Small' one-island map
----
----  First one to kill anyone becomes Mutant. Mutant has super-weapons
----  and a lot of health, which however depletes if he doesn't frag fast.
----  Goal of Mutant is to use his weapons to hold his status for as long
----  as he can.
----  Goal of others is to hunt the Mutant down. The one who kills Mutant,
----  becomes Mutant himself.
----  The player with least points (or most deaths) is Bottom Feeder. He
----  can gain points by killing anyone. Other normal players only get points
----  for killing Mutant.
----
----  Points:
----    +2 for becoming a Mutant
----    +1 to a Mutant for killing anyone
----    +1 to a Bottom Feeder for killing anyone
----    -1 to anyone for a suicide
----   other kills don't give you points.
