EDIT (9/21/2011):
New linkCoHRadar uses a demofile created by the client to create a 2D map of all game entities that your machine has been told about.
The map is useful as it can highlight were a hostage, glowie, or even where Quantum and Void-type enemies may be.
Just a note that it doesn't where any of the walls/boundaries are (and can't without decompiling the PIGG files), so you'll have to take into account when using it for navigation.
Those of you who have been around a while may remember the old "Blinkie Finder" program that was created around I6/I7. I used this as my starting place and reverse-engineered a lot of the functionality it provided.
Full instructions can be found
hereAlso, the full source code is available in the JAR file and on SourceForge if you're curious/skeptical. A bug tracker and request organizer organizer are also provided.
