Here is a map I've made for siege use. It's based off of "Carentan" from Call of Duty 2.
Attackers get 4 siege ladders, 2 limber-able cannon(pics are a little out of date). Artillery horses and rocketeers are set to spawn with cannon/rocket. Explosives have been disabled due to most of the buildings not being destructible. The attacker to flag run-time is 1:00min.
Defenders get many swivel cannon mounted throughout the town. 2 mortars are on top of a building roof. ladders and sandbags have been placed to let defenders occupy the roofs. Several doorways have been done with 2 door props, to resemble dutch doors. There are 2 breakable doors into the fort, both have 2 destructible planks over the doorway. A porticullus gate blocks the main entrance into the town.
This is my first NW map, so feedback is appreciated. Feel free to use this on your siege server.
