Meanwhile, Valve has been working on the development of a Source 2 Engine as early as 2012. It was being done in order to update the update the outdated content authoring tools for Source. However, it was simply August last year when Valve finally announced the release of the Alpha of Dota 2 Workshop Tools, ported to a new engine.
Valve officially announced the release of the Source 2 Engine in March this year and the company made it free for developers. The Source 2 engine is apparently compatible with the new Vulcan Graphics AP.
Since it is being predicted that the two upcoming games from Valve are Half-life 3 and Left 4 Dead 3, it is quite natural to expect that they will be developed on the Source 2 Engine. In a recent Half-Life 3 speculation video, the UGC tools in a Dota 2 Update unearthed the code “h3l”.
Stay tuned for more updates on Half-Life 3!
