Undeads are walking: Blue Blood

It is the year 20XX and something bad happened to Earth and humanity, but much worse to humanity to be precise. The thing it has happened, it is known as a zombie apocalypse by the modern generation.
The second volume of the series Undeads are walking is here.
This volume will be focussed this time on the journey of four teams.
One team of survivors and two Vikings creating rampage all over Sweden.
Second team consisting of scientists getting captured in a cannibal African tribe.
A third team of Indian singers getting blocked on a record studio in India.
And a last team, being stuck on a village in Serbia with a psychopath.
Prepare your guns.
