A good game nonetheless...
It was pretty good. I don't know why I keep playing, but that is a good sign, however in the three separate times I've played, I've never found her. Maybe it is my luck, but this last time, I cleared the WHOLE map and never found her. I even completed all the side quests to end up with a city that said Anna was no where to be found. It was very discouraging.
Repetitiveness:
My gripes come with the game's repetitiveness. The music never changed, and although fitting, was also maddening. The clues all basically said the same thing, giving no reason to actually read them. Again, this last time, I read through every clue I possessed, 64 of them, in a vain hope to find one that says "Anna was spotted nearby here." There were very few storyline clues, and even then, there was no reward to it. The guns and weapons were all fairly similar aside from ammo limits and certain properties. No one weapon was able to deal more damage unless it was of an explosive device. So... I ended up having a shot gun, and three assault rifles with me in the end. Though randomly generated, each city was pretty much the same with a slight difference.
Gameplay Quirks:
What irritated me, until I figured out the reason as to why it happened, was the placement of the rope ladders. It was frustrating not being able to toss a rope ladder on the run and escape up it when there are a few restrictions to it, like another rope ladder above it or an opening. Another problem was turning and shooting. It was sticky and I found myself unable to face the right direction and shoot. I'd have to turn, wait, then fire. When surrounded by zombies, being able to have control over your character makes a big difference. Sometimes I'd find myself walking backwards and shooting.
It was a good game though. There is still room for polishing, especially the fact that there is no guarantee that you WILL find her. I kind of felt like I wasted an hour chasing after a dream. Dad should've known Anna was a zombie too.
