Skillset required to reverse engineer.

Programming knowledge
* Assembly
* C++
* Understanding of compilers
* Good understanding of structures/classes/inheritance

Tools needed:
* dissassembler (Ida and ollydbg are some of the common ones)
* MS detours (google it)
* Visual Studio (for compiling detours)
* Debugger (ida, windbg)

You can try writing a hello world.exe app and then try to reverse engineering it. You will be surprised how much assembly code gets generated just to print Hello World.

If you are comfortable with reversing basic exes, then you can start learning how to write detours. Detours are commonly used in writing cheat/hacks for the games, they take an existing piece of code in a program and allow you to "detour it" and have it call your code.

For a game like matrix online, you can take existing server code/binary (HardlineDreams or Reality) and make a local server. Then you can try finding out (with dissassembler) pieces of code in the client.dll and matrix2.exe that do something in particular, like how to handle requests from the server for chat etc.

There is enough information on the web on how to reverse engineer. You do need to learn a lot of things, have some good puzzle solving skills and tons of TIME and patience.
