Help me, please!

Hello, everybody. As a Chinese who just know a little English, I do cannot understand the options listed below. May anyone do me a favor to tell me the meaning of each option in easily understanding sentence.

Thank you very much!!

Here are the options that I cannot understand.

get powerlevel closer to the servers average on dead
multiple ps'ing in free fighting mode
force respawn
lock models
low ping server physics

1. when you die your powerlevel gets closer the the average powerlevel of everybody in the game
2. people can do a multiple powertruggle in a free-for-all game
3. when you die it makes you appear again almost instantly, so stop people just being idol and dead
4. lock models prevents people changing their model that they appear as.
5. dunno exactially how it does this, but its pretty explanitry
