The nearly rogue-like experience of Hitman: Freelancer follows the epilogue of Hitman III, with players now able to approach four distinct campaigns with strategic planning to find items such as the powerful Silenced Pistol in a fast and efficient fashion when going after certain targets. Centered around Syndicate enemy bases, players of this expansion can build their arsenal through trial and error during these single-player missions, including one that places them near a section of the North Atlantic called the Isle of Sgáil. A Silenced Pistol is hidden under the base for players to add to their arsenal of gear for the future.
