The map is asymmetrical, and most fighting starts out on the sides and the central market, but after about a minute of game time, the battle becomes 360-degrees and can literally be anywhere, from any direction. In Horde mode, the bell tower tends to be the most common defense point due to its abundance of barriers, a sentry gun, weapon spawn and decoy. Additionally, enemies can only approach from two sides. However, this can become problematic if a Berserker or Lambent Berserker boss round is initiated, as the few entrances also means fewer exits.
