Dota 2 is now available in its shiny new Source Engine 2 form.
Opt into the Dota 2 Reborn beta to check out the rebuilt MOBA right now, if you fancy it.
Instructions on how to install the new, in-development version are available on the Dota 2 Reborn hub.
The latest hub update provides many more details on how porting over to Source 2 has improved Dota 2 and made it future proof. The new engine allows for reduced input lag; enhanced performance on low and high end machines; multi-thread CPU usage and streaming; better audio, physics and rendering; future support for Linux and Mac clients; and a tiled map system – meaning you can play together with people using different custom tilesets.
Reborn also supports the latest version of Source Filmmaker, and takes advantage of better networking.
