City of Steam

City of Steam is a free-to-play browser-based MMORPG created in Unity 3D and a number of other in-house tools. This makes it a very light and accessible game, needing mere megabytes of space for even the most detailed levels. The entire world, called the World Machine, is an ancient mechanism of gears, pipes and machinery, parts of which have long-forgotten or even entirely unknown functions. Even down to the smallest detail, City of Steam's world is industrial fantasy at its best.
