There have been lots of rumours going around the internet recently, about Half-Life 3 and Left 4 Dead 3. A trademark was filed regarding Half Life 3 by Valve themselves on 29/09/2013. And back in August following some naughty spying on a trip to Valve's offices, some information was leaked about Left 4 Dead 3 source 2 and engine 2.

Now the database has been raided again, and more information has been posted online. This time it is a full list of staff that appear to have been selected as part of the teams to work on Half Life 3 and Left 4 Dead 3. The Half-Life team is quite interesting, as it contains lead writer Marc Laidlaw, series composer Kelly Bailey, and series designer Steve Bond. The creator of Minerva Adam Foster and Portal Writer Erik Wolpaw is also selected.

The Left 4 Dead 3 team is much more surprising, with Valves names like Chet Faliszek and composer Mike Morasky. Clint Hocking of Far Cry 2 success and Doug Church of System Shock 2 aa part of the project. Of course we do not know how accurate this is, as it could be just some ideas Valve had at some point, but as soon as the news becomes concrete, we will be there to let you know. Comments below on these rumours.
