During the tournament DOTA 2 International , some gamers have been able to take a picture at one of the monitors present in Valve's offices. In the pictures, which were found at the bottom of the news, you can see clearly the title Left 4 Dead 3 and the Source Engine 2 with Ted Carson message that refers to some tests carried out on the play and went to fruition.

Currently, however, both projects have not yet been officially announced, although in the past, the Managing Director of Valve Gabe Newell had confirmed that the company was working on improving its graphics engine.

This means the next announcement of a sequel to the well-known co-op horror title, perhaps for next-gen? For lovers of Half Life instead there will still be in wait: the photo is not leaked anything.
