Hi everyone, I've been away from the Halo community for quite some time, and would like to start messing around with modding. Although there are many tutorials and resources out there, I am very overwhelmed and don't know where to start.

At the moment I'm more interested in being able to modify gameplay rather than making guns / levels. Can someone give me some pointers as to where to start? Also a list of the (latest) necessary and useful programs would be nice.

Any help is appreciated
