Rooftops is a multiplayer map.
Weapons which can be found on this map (when "Weapons Swapped" is off) include:
Boltock (2)- One on each team's side of the map.
Hammer Of Dawn (2) - One on each team's side of the map, in a small dark shack-looking building.
Longshot (2)- One on each team's side of the map.
Frag Grenade (2)- One (pair) on each team's side of the map, on a walkway over-looking the Longshot spawn.
Torque Bow (1) - One in the center (highest spot) of the map.
There is a hidden easter egg on this map. To see it, go to the dark side of the map (darker and stormier side) and stand in front of the doorway of the Hammer Of Dawn shack, with your back facing the Hammer Of Dawn. Chuck a Smoke Grenade, or fire a Boomshot round (if you set "Weapons Swapped on and put a Boomshot on the map) into one of the broken windows ahead of you and look closely. You will see a dead man sitting on a toilet.
