Hi, I changed a few things about the description of the game, trying to explain the game has been more hard than I thought!, I've been describing the game as a top down stealth game but I think this could me misleading.
I think that in stealth games people expect to have precise information about the environment before taking action (cones of view, visible sound reach, detailed maps) something like Mark of the ninja, but the gameplay in this game has a lot more in common with Metro 2033 and survivor horror games.
So now I'm describing the game as an open world survivor horror game, if somebody has played the kshatriya level from Metro Last Light, is basically that but the full game.
I'm also working in the sewers modules, the main purpose of the sewers is to serve as fast travel and a few mission areas, the level still needs textures and more variation but I already defined the places this props are spawned, so I can just create a bunch of prefabs later and let the level choose them.
The prefabs in blue can be replaced with another prefab of the same category, like: propsUp, propsLateral and propsDown.
