Wonder if they'll mix it up more for L4D3. It's kind of like the FPS equivalent of an arcade brawler as is, and that's why I've ultimately become before/apathetic about the series. Something a bit deeper would interest me much more.
Man people are going to be pissed this isn't HL3. Or they'll twist it into HL3 teasting anyway.
This would be really horrendous news so I guess I can only hope it is some elaborate ruse or that "L4D3" is still a code name for something more interesting.
I went and played through L4D1 with my girlfriend a few weeks ago because I figured it'd be an easy/simple FPS for her. We both had a blast even playing on easy. Such a great game.
