II liked the addon - It was fun.
although the game was fun and I enjoyed the random new dialouge lines
"WOO suitcase full'a money and pistols"
I have to say that I had expected much more interation with the original survivors. The simple fact that they are statically added and the only real interation with them is choreo'd -- It made me kinda sad.
That being said, this is ValVe, its not like I didn't like the add-on. The addition of the golf club was great, I love the solid metal sound it makes on a zombies head. The random caches were also fun - I'm glad that they were added to the info_weapon_spawn entity so that they are ranomly placed when the level compiles.
The addidtion of the new "uncommon common" infected is great, I've often wondered why this wasn't part of the original game. These can't be the ONLY people who are or were survivors.....
The new zombie likes to drop multiple things so killing them is a decent bonus to the game play and got me out of several sticky binds.
the story was fun but it seemed to take a little longer to actualy understand 2 things:
1. What the hell was going on
2. How the hell you were supposed to get to where you were going.
I knew I was supposed to get to the genorator for the bridge, but the path there was well - a little to obscure in my opinion. Though - I did enjoy the jazz club, the pool hall, and even the sewer area as I love playing the pitch black areas of left 4 dead.
It saddened me for about two seconds that the finale was a scavenge match, very simalar to Dead Centers finale. Though, this one was more like an actual scavenge match -- well done valVe.
Now- the peice de resistance, the M60. The gun was a great addition to the game and its achievment as well. Though, I was saddened when ammo staches did not replenish my ammo for it. It was great to destroy zombies with a high powered Machine gun the likes of which valve has only introduced in TF2 with the heavy or in DoD:s with the MG classes.
All in All I'll give the addon [85/100]
that translates to
[9/10]
[22/25]
[38/50]
roughly what i would use on those scales, those are not the actual mathematical translations.
