After the success and appraisal that the Russian-based development team Nival Interactive achieved with Silent Storm, the team decided to present us with its expansion pack named Silent Storm: Sentinels. The expansion starts right after the Second World War. It follows the adventures of a team of Spec Ops veterans, dubbed The Sentinels, whose main purpose it is to remove all possible threats to world peace and stability. In this particular case, the threat is represented by an organization named Thor's Hammer. You find yourself in the middle of a war against terrorism and espionage. (How fitting. – Ed.)
