Left 4 Dead 2, the co-op zombie shooter by Valve, is possibly being rebuilt using the Source Engine 2.0, according to a leaked slideshow presentation.

The image first appeared on NeoGAF, under the title “l4d3” (Left 4 Dead 3). Looking at it, it’s easy to see why one might think this is a whole new game – the amount of details is indeed impressive.

But this leaked image doesn’t necessarily means a new entry in the Left 4 Dead series. Rebuilding maps of existing games with a new engine is a great way of showcasing its prowess. Still, it eould be nice to hear more from Valve in the near future, be it about the new Source 2.0 or a whole new game.
