the idea is a level type in which you must shoot arrows attached to a string to lower platforms. standing on a certain spot where a bow and arrow have been left behind by some unknown wanderer then aiming with the keys or mouse and firing, since the arrow is attached to a string, when you miss you can simply rope the arrow in and retry to hit your bullseye shaped target. you travel along the rooftops using theese to jump from one building to the next with a choice of which way to go and for each player in the party there could be a zipwire per player, when going solo the other 3 spots would be missing the bow. the way of shooting an arrow is by using the keys or mouse to change facing direction, then using the attack to charge a shot just right to hit your target, trying not too overshoot or fall short.
chossing which way to go relies upon the entire party to stand on a row of zipwires, just like standing on those party buttons. each row would lead to different rooftops.
if theese arent included in their own level, i see no reason not too have them here and there in other city based levels. but either way works, and both are up for debate. another thought is that like keys, you must carry an arrow to your bow from another area.

uncertain myself, but i would like to know what people would say to this.
