Hi, I have found a lot of offer in online for hacks or cheat code for most of the popular games. Does anyone know these are real or work? And also tell me whether these are legal or illegal.

For cheats,
go on CheatCC.

If its legit, its on there.

For hacks, it can be a little questionable and I ain't legal advice. Nexus does mods but that isn't what you're looking for. Its also generally frowned upon to use hacks in online games for obvious reasons.
