[Retribution]

hax are actually pretty rare, i mean theres a lot out there and there easy to get your hands on, but few people are actually sadistic enough to use them
one of the main problems in this game is that people don't understand how it works, see when you try to make a real time experience with people all over the world theres going to be problems, and one of the biggest is that what you see happening and someone else sees happening aren't always the same, the difference in the time one receives a signal is very important, and the difference can be extreme
this can cause such effects as one appearing to shoot or see threw a wall, or even someone who would appear not to be getting hit while your shooting at them
others can be explained by one underestimating another's intelligence, like the case of the wall hacking demo-man could just be boiled down to good timing and luck
