'Go Back Home' is firts entry from Stephano Lessa at MSDN. It's a city themed newbie-looking level. It has all those beginner bugs like bad textures (at times very bad - building texture changes in the middle of building - see screenshot), buggy sprites (signs will follow your eyes) etc. (couldn't find much misaligned textures). Puzzles were a bit strange. Once you enter street (looks pretty good by the way if we compare it to other sectors) area you may exit the level by hitting nukebutton any time you want so you don't have to go through all those three key card doors (last one of them is completely useless). So why this? I have no idea. Rooms are lacking in details and shadows.
