An ancient piece of software the for some unknown reason large publishers like EA still use.

The staff at Punkbuster write their code in Java and only work on it from 9-11 am at the local community college computer lab.

The program mainly functions as a lottery system, if punkbuster works you are allowed to play the game that day.

This helps publishers pay as little as possible for servers as they force large portions of the community offline in a load balancing technique.
Punkbuster wont let me play my game online!

oooh bummer, better luck next week.

An anti-cheating program used by Quake 3 and America's Army. It updates alot, but still talented hackers/cheaters can cheat.
Non Cheater: Man, Punkbuster sucks. I gotta wait four minutes to update, and those losers still cheat!

A gay ass peice of shit anti-hacking game software. If you do not know a lot about computers or you have vista, chances are if you get a game which has punkbuster enabled for multiplayer, itll give you many errors. yes punkbuster does prevent hacks and most people do not get kicked from it, but its possible that you fall into the small category of people being kicked by punkbuster daily, for no reason at all.
"Hey 1337nub25, like my new server for COD?"

"No, I keep getting kicked by lame ass punkbuster."

"Punkbuster Online Countermeasures"

Anti-Cheat software from Even Balance that should prevent people from cheating in the games it is integrated with. Possible source of nuisance because of no backward compatibility, and many updates every once in a while.

See wallhack
When you go play Quake3, and you just started getting on fire, and suddenly you're "forced to spectator mode until PB version updates", you know what time it is.

An editor of UD, not to be confused with the uneffective Anti-Cheat program. PunkBuster is busting the punks that try to make UD a terrible place as we speak.
I'm leet-er than you. Noobs.

PunkBuster is an online anti-cheating protection software for known games Counter Strike, Wolfenstein: Enemy Territory, and other games with online capabilities.

While the sole purpose is to disable cheats, hacks, and botting on selected servers, PnkBstrA and PnkBstrB executables can lag some machines majorly. However, it still fits to execute its intended role.
PunkBuster was right for me. When we mean NO BOTS, we MEANT NO BOTS! Now my server is a play-fair server that everyone loves to log on to!

I just hope my friend's sorta-slow computer doesn't lag because of PnkBstr Processes. After all, he only has 512MB RAM.
