Hacks can include flying, speedhacks, etc. Since the game is in such early development, an anti-cheat/constant monitor is not implemented, so hackers are rather common even on the official servers (unfortunately).
Tip: Most, if not all, hackers are still susceptible to death. If you encounter a hacker, you are advised to log out or secure yourself. If none of the above are applicable, you may attempt to kill them. Most will die from 1-2 shots to the head with any powerful weapon (M4, Shotgun, etc.).
This is a list of current features of some Rust cheats that have already been released.
Feature Set Removed due to giving out names of hacks - we do not want people getting any ideas. Thinking of ideas? Know the Valve Anti-Cheat (VAC) bans permanent; you will not be unbanned! VAC bans failing, server administrators will ban you permanently from their servers with much haste. As a completely final warning, just about every 'hack' comes with malware or other unwanted programmes.
