HONG KONG ZERO HONG KONG ZERO

A free first-person action game set in real Hong Kong streets. Move between districts and moments in time, explore the city and complete missions.

Whiteout Causewaybay

You may know Whiteout Causewaybay from unwire's coverage: the first-person shooter web game played on the snowy streets of Causeway Bay. It is now the first district of HONG KONG ZERO, and the original game is still free to play. From SOGO and the tram lines to Percival Street and Times Square, complete three missions between blizzard and neon.

Counterfire Tsim Sha Tsui

Walk into Tsim Sha Tsui by the Clock Tower, the Cultural Centre and Victoria Harbour: rescue civilians, stop the courier, then break the last line of defence and defeat Grey Tide. The enemy is already in place when you start; you don't need to clear every guard.

Gale Nathan Road

The third district is Mong Kok. The Three Robber Kings join forces for the first time, planning a big job across Sai Yeung Choi Street South, Ladies' Market, the Mong Kok Road footbridge, Nathan Road, and Langham Place. Across five missions, retrieve the dim sum order sheet, rescue hostages, take the footbridge, defuse bombs at gold shop entrances, and finally defeat the mastermind under the giant screen.

Real Hong Kong & Inspiration

The districts are built on official 3D models from the Hong Kong Lands Department's CSDI spatial data portal, with OpenStreetMap road data and the game's own art repairs. The snow in Whiteout Causewaybay was inspired by the Causeway Bay snow battle in the film Sons of the Neon Night. This is an independent work, not an official game of the film.
