Locked Shields: The world's largest cyber-war game

Tallinn, Estonia - Things are bad on the small island nation of Berylia after a diplomatic row with Crimsonia, its bigger neighbour and rival. There are street protests by the Crimsonian minority in Berylia, which then suffers a wave of cyber-attacks that make it lose control of its drones and its only international airbase. Crimsonia is blamed for the cyberoffensive even though there's no hard proof. Crippled by the attacks, Berylia, a new member of the North Atlantic Treaty Organisation (NATO), weighs its options. One of them is to invoke Article 5 and take the military alliance to war against Crimsonia.
