Hate to rain on your parade but...
We received our copies at work and I got to play 3 or 4 missions. First of all, this game is short, and by that I mean really short. There are only 6 missions but you can beat the missions in 30 min. Graphics are OK but lots of tearing going on even if you are standing still. The voice acting is just messed up. Locke sounds like a 20 year old guy and Charlie sounds like a British guy. Gameplay is all over the place. There's no exploring, you basically have to do whatever they tell you to do. For example, you lost your camera and you go to the wreck and you find it and you go back to the beach and they give you a new task.
I'm a huge Lost fan but the game just doesn't make sense. Nothing feels right and the storyline so far has nothing to do with Lost the TV show.
