GameMenu.res

GameMenu.res is a RES file that is located inside the resource/ folder of the game / mod. It is the file that controls the menu buttons that will appear in the in-game menu. Mods can use this for adding new command buttons to their main menu.

They are simply a text document saved with a .res extension inside the resource/ folder. Example syntax (from HL2):
