Outskirts vacation

The rooftops of Old Mombasa.

The Rooftops Vacation, or simply, the rooftops, is a small programming oversight, similiar to The Delta Halo Vacation, The Metropolitan Vacation, and The Cairo Station Vacation. it allows you to reach areas of a level previously thought to be inaccessible. This is found on the level Outskirts.

How to reach it

Enter the courtyard and kill all the enemies until the hunters come out. Kill them as well. Then go through the tunnel-type thing the hunters made, but do not continue through. Instead jump on top of the protruding wall. Then crouch jump onto the wooden support beam overhead. You should see three pipes coming out of the wall and into the ground, of progressively larger heights. Jump onto the bottom one and crouch jump onto the remaining two, and then the actual roof. Now you can roam around this part of the level, and find a bunch of neat things to explore. I found a sniper rifle inside a little room once. You can not, however, reach the next part of the level this way; you must go through Hotel Zanzibar to do that.

On Outskirts when you enter the courtyard run past the jackals and on your right there should be a small gap between buildings. Go through it and it should look empty but if you look where the grunt picture is on the wall there is a ledge above it that you can crouch jump onto. Once on, run and crouch jump to the top of the building and you're on top of Outskirts. You can stay on top until you reach Hotel Zanzibar.

Alternatively: Right at the beginning of the level, before you kill the first grunt and right after leaving the crashed Pelican site, jump onto the light fixture across from the door, turn left and crouch-jump onto the roof, as if you were going to the Blind skull, except turn around and jump across the gap away from the skull and with the crash site now on your right. Grenade jump onto the ledge to your right and now you can explore all the rooftops in the city. Alternatively-alternatively, go up to the roof as if to get the Blind Skull, but instead of turning left into the hallway, go straight ahead to the ledge, stand on your partner's head, throw a plasma grenade on him, and time your jump so that you land on the roof. Note: this method requires co-op and takes a lot of practice getting yourself to stay on your partner's head without drifting.

Different Vacation in the second part of Outskirts

There is another vacation in outskirts that was found recently. Here is how to do it. After going through the hotel Zanzibar, get in the warthog and drive to the smashed Tunnel. I recommend destroying the Phantoms Turrets to make it easier to get on top of the tunnel. Now, see where the Phantom hovers and drive the warthog against the small ledge closest to the opening. Jump onto the warthog and onto the ledge. Now face into the tunnel, towards where the ghosts are parked. and you should see a small ledge small enough for you to jump onto the roof of the tunnel with. Have Fun!.

Easy Way To Get On Rooftops

My friend and I found out a really way to get outside of the map onto the rooftops on cooperative. You never have to fight any enemies. When the level first begins, have your friend turn around and jump ontop of the pelican. You must then jump on top of your friends head. You may have noticed several broken steel beams that protrude from the concrete roofs. The way to get out is simply to crouch jump off of your friends head onto the beam above the pelican and walk onto the rooftop. You may have your friend commit suicide so that he or she will spawn next to you on the rooftops once you are up there. You now have free reign over the map. Hint: This has only been tested on heroic.

Once you get on the rooftops, jump onto the right rooftop jump down to the beige/orange building. Go strait and jump onto the heaters. Ftrom there jump onto the small roof in front of you and go through the shatered roof. There is an energy sword laying on the floor of the room.
