Just to know

i read on internet and saw some video (maybe fake, i don't know) of one hit kill and gold hack.
About gold hack, i don't trust it, but one hit kill could be possible, like was in vindictus.
Does anyone know anything about them?

Thanks

So, actually, the only "hack" is the windows user switch to get mobs freezed?
Or there is some other thing woriking?

All gold hacks are impossible and highly illegal, but one hit kill would be possible.
