A group of Dota 2 players invited to Valve’s offices have spotted references to both Left 4 Dead 3 and Source 2 on one of the computers.
A member of the group, who were there to take part in the International 3 tournament, snapped a picture of a Valve changelog on one of the dev’s computers. The image shows a line of text which mentions both Left 4 Dead 3 and the Source 2 engine.
Left 4 Dead 3 is yet to be officially announced, however the Source 2 engine has been hinted at several times and Gabe Newell basically confirmed that a new engine was in development during a fan tour last year.
