There was a city in which its citizens were treated with apathy by its government and its social elite, the people didn't had minimum conditions to live until one day they became living zombies.
The zombies kept living their lives as usual, without noticing the injustice and exploitation they were suffering, accepting everything the rulers did. It happens that a group of these zombies got Insane in the gore brain" with all that bullshit and incited the rest of the others to go on a "furious uprising collecting kills" to change that status. So the zombie commando started "melting the brains of the bastard fuckers" spreading "terror in the city of the zombies". To fight the zombie uprising the government sent the police to the slums, where most of the zombies lived, this event became known as "slum bloody gore", fortunately for the zombies the majority of the bloodshed wasn't theirs. The streets went red with the blood of the "lacerated cops". The commando didn't stop, it got to the city hall where all the politicians and rich people were gathering to put an end to the zombie revolution. The zombie squad became known as the "assassins of political scumbags" when they got out of the city hall "marching on the rich's corpses"."
