The Walking Dead Episode 4 has been unleashed with a new teaser trailer to help entice gamers. Author of The Book of Eli, Gary Whitta wrote on the PlayStation blog “undoubtedly the biggest and most ambitious episode so far in terms of action and choices”.

He added Episode 4 also introduces some brand new characters who should shake things up a bit, including one in particular that I’m very keen for you all to meet. Let’s just say that Lee’s group hasn’t encountered anyone quite like her before now”.

Remember, that The Walking Dead is set to be made available on disc. Further information is expected to follow soon.
