Ok, im wanting to start making hacks and i only know how to do:

Instant 70

Can sum 1 please tell me how to search for like.

Kills
Deaths
Time Played
Prestige
EXP
Etc..

Thanks.

Well I used to play on Killing Floor and to level my perks what I did was I searched the amount of EXP/kills/head shots/damage or whatever, I did a couple more of what the perk requires, search the new amount that I have in the next scan. There should only be 1, if not keep repeating the steps until it comes to 1 address left.
