Killing Floor Level 6 Perks "hack" question.

Hello, I've seen the thread about changing your perk level with cheat engine, but have no knowledge in that area and am lazy as of now, I wanted to ask though if the all perks level 6 stats.bin file works, and if it's undetected by VAC.
Thanks.

stats.bin replacement doesn't seem to work for me and my friends.

Using Cheat Engine works and I haven't been caught by VAC yet, tried it at least 3 months ago now.

The problem is that you can change your perks with C.E. only (I think so) in solo. I changed my ss and bs in solo. But when I go to server and try to change perks they changes and when I do more damage or make a headshot the changed perk goes back where it was. That's prob. And with stats.bin you'll change only your solo perks too (even if you know how to do it).

I play cracked kf. If you have original then idk what you can do with stats.bin or C.E.
