A City Sleeps is a shoot ‘em up developed by Harmonix Music Systems for the PC and Mac. Its action is driven by a blend of hip-hop and electronic music scored by M-Cue, and requires no beat matching.
The residents of the city of SanLo have fallen into an endless slumber, haunted by nightmares filled with demons. Poe, the youngest member of The Silk, an ancient clan of dream exorcists who battle demons in the minds of sleeping individuals, must save the population of SanLo. Armed with her Koto-sword “Heartstrings”, and supported by her stable of ghost familiars, she must cleanse the dreams of the SanLo population and get to the bottom of the city’s dark secret.
