ArchLoader is a utility to unlock the Halo 4 Network Test for offline, system link and online use. The beta was designed to be a limited-time matchmaking beta, but this will allow you to play Custom Games or Forge, and use the Theater. It also allows you to modify camera views (third person, flycam, etc) and change Direct X rendering modes (point or wireframe), among other tweaks such as Field of View and Time Scale. The module loads itself as a system dll so it can run in the background while the game executes, patch it, and hook into it, so the game will jump into code in this executable, allowing you to make changes to the game in C++ instead of patching assembly instructions.
