Cities: Skylines Expansion After Dark Release Date Revealed

After Dark will be available on September 25 for $15.

Paradox Interactive has announced that the Cities: Skylines nighttime expansion After Dark will be out on September 24, with a price tag of $15. Developer Colossal Order also posted the first in a planned series of dev diaries explaining why there's a lot more involved with making the expansion than simply turning down the lights.

"Taking the cities from daytime to night is not as simple as one might think," Lead Designer Karoliina Korppoo wrote. "While the change from day to night is visually stunning, there's much more going on under the hood. Each and every building in the game received a new texture layer to have the windows light up nicely. In addition there are new lighted signs, neon signs and other lights to make the city look interesting during the night."

"The night time creates new challenges and changes the way traffic behaves to alter the way the city works," Korppoo wrote. "We want to create more variation to the game and make the cities feel alive, with ever-changing needs and a constant, but changing, stream of citizens traveling to their desired destinations."
