Brink

In Brink, two sides, "Resistance" and "Security", fight in the outskirts of a utopian city known as The Ark, a floating city surrounded by the waters of a flooded Earth.[1] The Ark was designed as a prototype of a perfect city, with renewable resources and no pollution, large enough to support 5,000 residents. Its population has grown to 50,000 however, leading it to the brink (hence the name of the game) of a civil war
