Shadowrun Chronicles - Boston Lockdown is a turn-based, tactical role-playing game set in the Shadowrun universe. The game requires an online connection and is meant to be played in cooperation with other players, although it is also possible to play alone.
The game is set in 2076, and shares the timeline and metaplot of the 5th edition of the Shadowrun pen-and-paper game. As its name implies, Boston Lockdown takes place in Boston, as the city gets quarantined following ominous events: the awakening of an unknown Dragon, a mysterious, rainbow-coloured rain, and a pandemic of people getting insane. As in any Shadowrun plot, things quickly become messy, with gang warfare, corporate shenanigans, and different agendas pulling the strings in the shadows.
The player plays a “shadowrunner”, a mercenary doing dirty jobs for the Megacorporations and other shady clients. After meeting NPCs (and other players) in a “hub” environment, the player(s) can use the map of Boston to tackle various missions (“runs”), earning nuyens to buy better equipment and karma to improve their skills.
