Perhaps players using a powerup (Invincibility, Infravision, etc.) should get less points, and killing a person with a powerup gives more points.

I like it. It really solves the problem of people staying dead, and when you nearly killed someone. I agree with Jackal- it'd be cool if a lower-tier kill was more points-worthy than a rocket or napalm kill.

This is a very cool script. It balances out the problem of players with less deaths and less kills being ahead of those that potentially did better. What would be really neat to see would be for the damage not to be based off of the physics. While this would complicate the script much more, it could be very interesting- e.g., a magnum kill would be worth more than a rocket kill.
