Me neither really. I enjoyed the first one more. Dual Pistols was all I needed in that shit. I just rifled tanks and that was it.
The second one had it's moments, but the heroes sucked ass. You have the redneck, the arrogant douche, the stereotypical black chick and the fat black dude who loves chocolate. All lose, all the time. The only good part of L4D2 was that they re-did some of the L4D missions with the OG characters... including the aforementioned Bill Death scene. They're way more fun. Melee weapons are definitely nifty, but L4D2 just didn't do much for me. Not sure why.
