A free to play browser-based MMORPG created in Unity 3D (and loads of other in-house tools)
Developed by Mechanist Games, City of Steam is a browser-based, free-to play online RPG set in an industrial world poised to rediscover the mythic forces that shaped its history. Clockworks, steamworks, combustion, and alchemical principles suffuse the nations and people of the World Machine, pushing heroes and villains alike toward a dangerous secret that could change everything.
The open beta test of City of Steam has started today - new features and content will be added to the game on an almost bi-weekly basis. The Vault, an entire new suburb (hub) is scheduled to be released this month, and an additional suburb will follow soon after. New features like events, a fully streamlined skill, talent and crafting system and substantial amounts of cosmetics have also been added to the game.
