This place has only one rule: RULE IT!
Or you can only beg on your knees for room to breathe.

Power is the only identification that distinguishes you from the mobs.
Black or white, blackmail or negotiation, there is no clear definition of the same action
Only the winner can judge.

Let the beast in you take control, bite and tear apart your enemies in the darkness
And you can survive

And how to be successful?
Have a good timing, seize your chance tight, be elegant under pressure.
And most importantly, be powerful.

This is the city!
I am here to make it mine!
Do you surrender?
