Santa came a little early and delivered a copy of Left 4 Dead 2. Alright, so it was Dan (sorry to ruin that it wasn't really Santa) but that was great because we spent quite a bit of time going through it. Managed to get through the whole thing as a matter of fact, and it was quite a rush.
The mechanics are the same as in the first Left 4 Dead. There are some new items that were introduced as far as health, weapons and projectiles (specifically, Boomer Bile which can attract hordes to other creatures like the Tank). You also have some new special zombies added, including the spitter which gets acid all over the place and (my favorite) the jockey which rides you around. Dan led the way, so unfortunately he took the brunt of the damage from a lot of Jockey attacks (not to mention a significant amount of friendly fire from yours truly), but nothing too serious.
I do wish Valve would have kept earlier promises about giving more content for the first Left 4 Dead, instead of coming out with this game, but all-in-all it's a fun zombie slayer.
Bottom line: While there was some controversy about undelivered promises over the first Left 4 Dead, this is a very good game and quite enjoyable to play. I mean, it's zombies for pete's sake.
