This is a low poly game map. It can be played fluently on any device, even your smart phone.(I only use diffuse shader to deal with this map in unity and it works well on the 3-year-old mobile device.) It haven't been baked yet. You can place lights wherever you want and bake it. Feel free to use it. The origin authors belong to Dazad Game Develop Team. The map is also one of the maps in Local Warfare: World Campaign and Local Warfare Portable.
