Perhaps players using a powerup (Invincibility, Infravision, etc.) should get less points, and killing a person with a powerup gives more points.
In this script, the scoring method is changed so that every time you deal damage, you gain points. Kills and deaths do not award points. Watch out and don't damage yourself because it will take away points and suicides usually hurt more than help you.
Just select it when hosting and set netscript as your gametype.
