I'm sure you've encountered this at least once - you'll be playing in Highrise and someone will be camping beside the fuel tank, on top of the elevators, and won't budge. So, you try to flank them - but there's a Claymore sitting at the top of the ladder. Well, there's a simple solution, though it can be tricky and may result in a few falling deaths.

First off, I'd recommend Ninja so if the camper has a heartbeat sensor, he won't find you, since you'll have to get up close and personal. You know how you get onto the crane to snipe, and get up top in the one building? Normally, you'd go from the camper's position up top to get onto the beam and walk across. There is, however, an alternative. You simply have to get around behind the elevators, on the ledge. Then, jump for the beam, and press your jump button again so you climb onto it, and then you frag your camper from behind.

There is a trick to this though. If you don't do it properly, you'll miss completely and fall to your death. Once you're behind the elevators on the ledge, you have to face the beam, sprint towards it, jump, then press the climb button all within a split second. It'll take some practice, believe me. Mistime anything, and you drop like a rock.

Once you master this, you'll be fragging n00b campers in no time!

Yes this is a right pain when faggots do this!

You could also go on the cranes near the centre of the map and then probably shoot them, iirc you would be high enough. I would have to test this theory out though :/

I don't think that works as the tank is in the way. If they're not paying attention it might work but IMO my method is the best.
