The Gustav is a closed source C++ hack for Battlefield: Bad Company 2. It incorporates realtime physics simulation to determine potential targets, as well as unique D3D hooking to provide visual cues for the user in the game world itself.
It has taken me about three months of tinkering in my time off to put together and I am more or less satisfied with what it has taught me about physics and reverse engineering, which are two subjects that are very easy to unlearn without practice.
I have written up a couple pieces of interest encountered while developing the Gustav, namely how to draw in 3D within the game world while respecting Z-depth and a short primer on how to write a tree-recursive menu, the latter of which will probably be nothing new to any experienced dev.
