Specific Action: The shifter will walk over to the bridge and check it out. He is going to be looking to see how sturdy it is and if it I capable of supporting weight. IF he finds that it can he will slowly walk out onto it going slow and testing the strength of the bridge as he moved forward up to the edge of the broken section if it continues to hold. He will check out the broken section and see how far across it is to the other side. If at any time the bridge acts unsteady he will move quickly back to the safety of the room where every one else is at.
Assassin looks for a small rock or some pebbles and throws them into the darkness below to see if he can get some idea of how far down the drop is from where he stands.
Assassin waits on the others but flashes his light above to see what the bats are doing and where they came from.
Rasputin will crawl upon the bridge with his hands and knees in an attempt to avoid breaking it. When he gets to the spot where the bridge stops, he will swing his grappling hook and fling it across in an attempt to snag the hook on the other end.
