The Old City is a first person adventure game that focuses entirely on story. Everything else is secondary. Set in a decaying city from a civilization long past, The Old City puts the player in the shoes of a sewer dwelling isolationist. You progress through the game by simply exploring the environment. The story itself is told via the musings of your character and, chiefly, the environment itself. There are no weapons, no items, and no skill-trees. All that exists is you and the world.
These three busts, sculpted by our awesome sculptor, Josef, are associated with the 3 tangents of the game. After the prologue, the game actually splits off depending on your philosophical leanings, and seeing the other tangents requires a replay.
Ingame, of course, they won't have the PostMod base. But, those bases are important for reasons that you will discover in a few days!
