Sometimes when you hit an opponent you shoot him/her into lava, slime or other hazzardous areas. You have caused your opponent to die, but you don't get any points for it.
This mutator checks for that kind of kill and awards you the points you should receive because you were responsible for the kill.
The mutator doesn't make a difference between opponents and team mates, it only tells the game that a push kill wasn't a suicide, but a kill. Then the game will decide whether points are added or removed.
The Who Pushed Me mutator for UT 2003 has been released.
In short this mutator removes the injustice when you push someone into lava or open space, but instead of you getting a frag your victim looses one for suiciding. With Who Pushed Me the game will handle these kills like regular ones, i.e. you will get your frag or loose one for a team kill.
Who Pushed Me is out now, so get downloading already. ;)
