There is some old cum-stained and whiskey-smelling mattresses up here, lots of bricks, and a bashed-up bed frame. You use them to barricade the door leading down into the building that you are on. You are pissed off at fate itself; you've been cheated and now you are almost certainly going to die! Fuck!
You forage the circuit around the rooftop finding a couple abandoned pigeon hutches, a half dozen tires, and a armload of scrap lumber. These you can use to fortify your barricade further with.
Not only that, but you found a pint bottle of vodka, with one third of it's contents left. There may be some justice left in the universe...
