The next Left 4 Dead game may run on the source engine 2 thanks to a leaked photo from a Valve Tour posted on Reddit. In fact, it is no secret Valve has been working on a new engine, when Gabe Newell said the following during a fan event a few months ago:
We’ve been working on new engine stuff for awhile. We’ll probably just roll it out in one of our games
What game could this be Mr. Newell? Well, according to the hard-to-see image above it could be left 4 dead 3. Furthermore, a user over at Neogaf resized the image to get a better view.
2013/8/5 14:55 Ted Carson [Source2] Restored L4D3′s devtest unit test. Ran locally 6 times without an assert. This may be so…
Of course there is no confirmation from Valve themselves. So, while this is good news, we will just have to play the waiting game on this one for now.
