In the May issue of Game Informer (available now in their digital issue), the first screenshots of The Wolf Among Us have been revealed. The art design enhances the playable comic book feel of Telltale's The Walking Dead tenfold.
The issue also reveals more of the "Fables" that we'll be encountering in the game. There's the ones we already know: Bigby Wolf (the big bad wolf), who's the sheriff of Fabletown, and the person we'll be controlling, Mr. Toad (who is a carjacking thief, and who is able to keep himself and his family in human form to keep from getting sent to the farm), one of the three little pigs (named Colin, the one who built his house out of straw, is a professional mooch who lives on the farm with his cousins, but sneaks into the city since he's bored with farm life). There's also Ichabod Crane (deputy mayor of Fabletown for nearly 115 years), Snow White (the assistant to the deputy mayor of Fabletown) Beauty and the Beast (she's dependent on him (but is still said to have genuine care and concern for him), and he works two and a half jobs in order to keep up their lavish lifestyle now that they don't have servants), and Buffin (a talking, winged monkey from the land of Oz who is Fabletown's librarian, and prone to mischief).
There's some more information on how Telltale has evolved the gameplay from The Walking Dead as well. The action has improved. It will still be motivated by the game's narrative, and it will still be presented in a cinematic style, but players will have more control over the action (which in this game involve bigby throwing punches). And since Bigby is a Fable, the action will be more over the top than The Walking Dead since Bigby can take more punches than Lee ever could (and the amount of damage you take is shown in your appearance, and is noticed by the other characters in the game). There will still be quick time events (involving Bigby making a decision in the middle of a fight to decide the game's outcome). However, it seems the QTE's this time will be just the decision making ones and not the button pressing ones.
The relationship building in The Walking Dead will also be expanded in The Wolf Among Us, as it's said to contain a lot more of that, and there will be a powerful emotional connection to the characters like Telltale did with The Walking Dead.
As Telltale has said before, you'll be able to choose what decisions to make like The Walking Dead. The Wolf Among Us will also have the opportunity to choose when to go to different locations, making the events unfold in different ways. Two events will happen at the same time, and the other event will still unfold regardless of whether you've experienced it first-hand or not, giving the game an extra element of realism (and replay value).
