The first-person shooter adaptation of The Walking Dead by Overkill Software has been delayed. Again.

Starbreeze Studios, the owners of Overkill, announced on Friday that the game is now pushed into the second half of 2018. The last launch window given by the publisher was the second half of this year.

The Walking Dead was announced in the summer of 2014 and given a 2016 release window. It reappeared at E3 2015 where it was a proof of concept for Starbreeze's VR headset, said to go into production at the end of this year.

In January 2016, Starbreeze delayed The Walking Dead to the second half of 2017. That delay was attributed to plans to launch the game simultaneously in Asian markets.

The Walking Dead, a franchise created by Robert Kirkman and Tony Moore spanning comic books, television, paperback novels and video games, has seen two critically acclaimed seasons as a narrative video game developed by Telltale Games, and currently is in a third.

An earlier FPS, The Walking Dead: Survival Instinct by Terminal Reality and Activision, was a critical flop when it launched in 2013.
