A program written in C++ to remove and cleanup code flow obfuscation seen in a variety of Call of Duties titles.
A tactic created by Treyarch to make reverse engineering their recent titles a pain is to add junk instructions specifically targetting how IDA parses opcodes. What you end up with is a junk instruction followed by a call that loops back to a few bytes into the current location with junk opcodes that vary, making it difficult to scan.
