Is that going to be part of a whole scene where it is attacking a castle wall?
Also how does it work? It looks like the bridge part pivots? Does it start pointing straight up in the air or something and then crash down on the wall to make an access point?
It looks like your supposed to push it up to a wall with that top platform in the air, then drop it down onto the wall and a bunch of guy's run up the stairs and crawl threw the opening into the building under seige?
