Brief overview of the new Dota 2 Reborn Beta gameplay. Game running in 1920x1080 with all settings maxed except Vsync (turned off). Beta testing open in June 2015 and the official Dota 2 client will be updated to Reborn (source 2 engine) some time after The International 2015.
The gameplay is exactly the same as Dota 2 but with some aesthetic update. The texture of the map is different with the addition of more ambient creatures. Many gameplay bugs are present currently in the beta (obviously). Graphic options are similar to Dota 2 and the final version of Reborn definitely will look much better than this current beta version.
