A beginner’s guide to game hacking techniques [pdf]
I’ve done a fair bit of gamehacking myself.<p>When PUBG came out on the Xbox, I built a tool to sniff and parse gameplay packets to determine the exact location of loot and enemies.  Radar cheats are much more common now, especially because if the developers do not use any type of encryption, it is rudimentary to setup a packet capture with a 2nd PC or laptop.<p>On PCs where the communications are encrypted, I use a hardware device plugged into my motherboard to grab the encryption key directly from memory.
