Unfortunately many, if not all cheat providers have dropped support for H1Z1. I see many people asking for cheats and don't know where to get them. The answer is simple, pretty much nowhere. Luckily, thanks to the internets there are still 1 or 2 sellers, though you will need to identify yourself as if you were to visit a max security prison, so be warned. Here is a small list of current provider(s) that offer a cheat for H1Z1 in it's current state.
Proofcore.io
Proofcore re-released their H1Z1 cheat for the audiences. You can find it on . or trough one of their ads on this forum. It features an ESP and aimbot that works. It needs tweaking though, because from a distance it becomes a challenge to hit anything properly. What makes this one good is the fact that it comes with a set of options to make you rage or fight legit, simply because it offers those options.
There is a 7 day, 14 day or 1 month sub ranging from 24usdto 50usd.
You will need to verify yourself with an ID and a selfie taken with your ID. Verification can take up to 48 hours, so buying the cheat now doesn't mean you'll have it now. it's a manual process, but when you're in, you're good to go. You can find other h1 cheaters in their discord, they usually link your forum name to your discord and it'll show a h1z1 membership.
