This addon adds a chapter selector to the main menu.
This addon will let you select the chapter (sequence) you want to play all by the click of a button on the main menu.
Half-Life: Echoes Chapter select addon by Eden_Nation
For Steam Version
Addon is English only.
Instructions: Put the two files (GameMenu and gameui_english) into the "resource" folder and replace the two existing files.
Drop and replace files located in Half-Life\echoes\resource
Disclaimer: Loading into a chapter (sequence) will NOT load you in with any weapons or armor, only your suit.
Thanks to Gunship Mark II's Half-Life: MMOD for the inspiration.
Not sure if this will make it feel more like MMod or HL2. But I'm up for it!
