I have the same problem, sadly disappointed...
I prepurchased the collector's edition that comes the big comic book, which is nice. I bought this for my daughter as an early Christmas present when she returned from college. Something we could play/enjoy together, as we are both Walking Dead fans. I have already purchased this game on the iphone, which works wonderfully. So, you can imagine how I was anticipating with great excitement to play this on the XBox 360 for the first time. She tore open the box with glee, and everything looked cool. Then, we plugged it into play. We haven't fired up the XBox (4 gig, with 3 gig available by the way) in a while and were initially prompted with downloads to update the XBox. This took a while, because I have a satellite connection (albeit a high end satellite) for the internet. This connectivity is OK for browsing and some games, but not most (not sure if this matters). Anyway after downloading all XBox updates, we selected the Walking Dead disc and also had to execute an update (title update as I see referenced elsewhere). With all updates completed (including multiple reboots), we proceeded to play. While the HD resolution looked much better than my iphone version (as expected), I immediately noticed a degredation in frame rate, which I have never seen on any of the other XBox games that we own. I thought to myself...oh well...a little slow on the frame rate, but still playable...and my daughter didn't care. She didn't have anything to compare it to, so she thought it was great. However, we eventually made our way to the horrible, unplayable action sequences, which are articulated very well in previous posts (i.e. the zombie attack in the first house, and the farm where you decide which person to save). We can't even proceed past the farm scene as it eventually freezes. I tried multiple times with a reboot each time and get the same results.
I find it hard to believe that such a product of such a franchise made it out the door in this state. I want to believe that there is a solution. Do I need a better XBox? If so, what do I need? I have been purchasing and playing video games for decades, since the Atari 2600 days. I own an NES, SNES, N64, Playstation, WII, Dreamcast, and several computers, each with a large library of games; and, never, I mean never, have I seen this type of debacle. So, I have to believe that the problem is on my end. That is, my XBox 360 is not up to the task. However, from what I read on the back of the box (requires up to 256 MB for system updates), my system should be ok. I though it might be related to my slow broadband connection. So, I disabled my XBox from the network, ran the game with no internet, and experienced the same problems.
Therefore, we (the paying customer) need answers or solutions. While I don't want to purchase another XBox to solve the problem, I will. But, someone at TellTale Games needs to answer this plee for an explanation and instructions for the solution. And, if the game is just really this bad and nothing will solve it, just say so.
