I noticed this while deploying drop-uplinks in random locations.

If you start off at the objective B spawn point, head east to the road then immediately turn right (south) and head up the road a little bit, and go between where the pipes (i suppose) enter the ground, theres a little gap that you can get between (maybe not a heavy). If you keep moving between the end wall and the middle of the gap, there is a point, about midway, which will propel you upwards to get on top of the concrete structures holding the pipes.

Now you can't do much up there, or get onto the pipes (i think), but it's a good lil spot for a sniper. And unless my dropsuit has an inbuild wall climbing module, I don't think your supposed to be able to get there. Also this post may not be helpful, but if there are other structures with similar close proximity walling, this glitch may occur in other locations on other maps. (but then again I know sheet about building a map and the mechanics that underpin them)

Has anyone else done, or seen this?
(If my random ramble gets through to anyone)

I've been able to get up onto all of the pipe structures in the map. They make decent spots for the uplinks, as do the concrete structures around them. This way seems a bit roundabout, but if the angle of the terrain is right it should work.

When you say "propel upward" do you mean you're walking up the wall or that it looks like someone flicked the gravity switch and sent you flying?
