I think it was weaker than the other two episodes as well. I missed the kind of "wow" event like in Episode 1 when the Zombies enter the drugstore
and in Episode 2 when you decide about the fate of the two brothers (especially the part where you tell the second brother both his mother and brother are dead when you killed them... wow that was a really really intense part)
. In Episode 3 there wasn't one of these moments where I'd just afterwards sit back and think "wow that was awesome"
Tho it had the first actual shocker element in the game for me... playing the game very relaxed with headphones on and suddenly that zombie caught in the seatbelt tries to attack you
... that REALLY got me!
