New Fort Assault Mode!!???

Okay, Rezoner, don't hate me for this...(violating the one idea per week rule and deserves a ban) My idea is that there would be this new mode where you must survive (with others) against a horde of beasts in the fort. I really miss the beasts and how solid they are. You have to constantly gather wood to repair the gates against the beasts ( they will destroy your gates and attack you ). I also think that goblins can be a part of this new mode because they can help the beasts out ( Finally the beasts have a bro to rely on ). Once you reach a selected time limit, your game will end with a endless unstoppable horde of goblins and beasts. You also might want to tweak the map limit to prevent players from running from beasts endlessly. GIVE ME YOUR THOUGHTS PLEASE!!!!!!!!!
