Valve is reportedly working on developing Half-Life 3 and Left 4 Dead 3

Over the past few months and years, we have been hearing rumors that Valve could be working on Half-Life 3. After all, why wouldn’t they? The previous two Half-Life games have proven to be huge hits, and have managed to spawn mods that have become their own games, like Counter-Strike, for example. So far Valve has been denying the rumors, but according to Counter-Strike’s co-creator, Minh Le, Half-Life 3 is being worked on, along with Left 4 Dead 3.
