Zombie Game Back 4 Blood Next-Gen Cooperative FPS

Turtle Rock Studios the creator of the classic co-op zombie game Left 4 Dead, has been dropping teasers for their new co-op zombie game by the name of Back 4 Blood. The next images were posted by the company on their Twitter account. By the looks of it, it will be having an even more post-apocalyptic feel to it than Left 4 Dead.
By the images, it is suggested that possibly this will have a more tower defense feeling to it judging by the traps set in front of the base. Maybe this is a player made base somewhat similar to the Fortnite co-op mode in which players defend from monsters of the storm, but here it will be bloodthirsty zombies. But this is all a speculation because the company has not released anything new as of yet.
When the game was revealed by Turtle Rock Studios it was said it will be a “next-gen cooperative FPS” which will be similar to Left 4 Dead by the fact that you will be battling hordes of zombies here as well. But they said that there will be a whole bunch of new stuff added that will make it more unique than Left 4 Dead.
The game has no set release date but will be released for PC, Xbox One and PS4 (although, in 2019 a release on other platforms was said to not be out of the question so there may be a Nintendo Switch version and so on).
