Indications that Valve are working on a next-gen version of their Source gaming engine have been published in a blog
Valve fan site ValveTime has published a post that reveals that files found within Source Filmaker that make more than 60 references to a "Source 2" engine. The line of code posted on ValveTime state:' 'Return an str with the current engine version. If key doesn't doesn't exist, assume 'Source', otherwise invalid -- assume next-gen 'Source 2'.'''
The post reveals there are reference to Source, Hybrid, and Source 2 in the file. The author goes on to say: "We speculate that Hybrid is the base for which Source 2 is sitting on. Barnz also says it looks like Source 2 is using the same pipeline as Source, meaning that it will probably be keeping its .BSP level format. We haven't found any references to DirectX or OpenGL yet, or Episode Three for that matter, but we're still investigating."
The post also includes an update from another community member that details a list of icons for "Source 2 tools" hidden in the Filmaker script files. The code and icons are the clearest indication so far that Valve - the developer behind the Portal, Counterstrike, Left 4 Dead and Half games franchise - are working on a brand new gaming engine for next-gen consoles. It's also the first sign that a new Half Life game could be currently in development, which will certainly cheer Half Life fans, who have been waiting for a new instalment in the series for nearly five years. The original Source engine debuted on Counter-Strike: Source and Half-Life 2 back in 2004.
