Story
Well, there is no story. AssaultCube is a great game about two teams fighting each other.
The Cubers Liberations Army (CLA)
Little is known about the goals and motivation of this small but feared Terrorist group. Their activities are as diverse as their members. With ex-military, anarchists, religious fanatics, conspiracy theorists, hippies stuck tripping, free software fanatics, or simply severely mental disordered persons or bored youngsters, this organization is a pool for radicals from across the globe. Their operations range from simple annoyances (such as introducing large amounts of mariuana-smoke into the air conditioners of offices or malls) to well planned gruesome bombings, choosing civilians as well as politicians, lobbyists or religious leaders and their staff as targets. "Terror for the sake of terror, for you all suck!" seems to be their motto.
The Rabid Viper Special Forces (RVSF)
An elite group of armed special forces, but not the kind you;d expect. These guys are battle worn fighters and mercenairies, who might have been just a little too trigger happy and up for glory to fit into any other kind of elite squad. Not suitable where lives are to be spared and private or public property to remain unharmed. The backrounds and funders of this extravagant task-force remain well concealed, for obvious reasons.
Their primary targets are highly unpredictable terrorists and organized criminals such as the CLA where intelligence, infiltration and stealth would be just a waste of time. First shoot, then ask questions, if anyones left to ask is the primary approach to their job.
