From Cities Skylines 2 and Against the Storm to the upcoming Frostpunk 2, most city building games are all about expanding your urban sprawl across a wide stretch of map. That format gets a perspective twist in new roguelike strategy game Vertical Kingdom, however, which demands you construct your cities upwards into the sky in the style of a Terraria town, earning new cards and gathering resources to help construct your towering metropolises, and it's out now on Steam with a special Steam sale discount for launch.
