Teleporting Through Walls with Cheat Engine - "No Way Out" [PicoCTF 2023]

Walkthrough for a Unity game hacking challenge from the Pico Capture The Flag competition 2023 (picoCTF). First, we'll decompile the Assembly.Csharp.dll with DNSpy and patch/re-compile the code to retrieve the flag. In the second solution, we'll use Cheat Engine 7.5 to identify our player position and teleport through the wall, allowing us to recover the flag. Write-ups/tutorials aimed at beginners - Hope you enjoy 🙂 #ReverseEngineering #CTF #CaptureTheFlag #Pico #PicoCTF #PicoCTF2023 #CheatEngine #GameHacking
