They're is technically nothing server sided and nothing is patchable.
Combat arms uses the lithtech game engine(which is moddable).
Every lithtech game uses a file called attributes.rez. Attributes.rez determine the stats for stats,vest,etc etc. So technically nothing is patchable. The game engine uses attributes.rez to determine everything. If someone can use the game engine to translate the file then we can edit everything in the game. But one problem would be that the game checks if the files are edited so a extra bypass would be needed.
