Brink , a multiplayer shooter, takes place in a future where almost all of the earth is flooded and the Ark is one of the last remaining habitats. The security guards and the resistance are at war, with each side trying to gain the upper hand. The game features two single-player campaigns that are similar to the multiplayer mode but with added bots and cutscenes.
The gameplay revolves around completing objectives on various maps, with different areas having their own goals. The security forces and the resistance have opposing goals, leading to a cat-and-mouse game where players must work together or against each other. There are four classes: soldier (brute force), medic (healing), engineer (gadgets), and agent (hacking). Each class has its own set of mission types, including escorting, destroying, defending, and using devices.
The game utilizes an automatic mission system, where players receive missions based on their actions. Completing these missions rewards experience points that can be used to upgrade characters and unlock new abilities. Teamwork is a key aspect of the game, with players able to switch between classes in-game or create unique characters at character creation.
