Here’s a crappy MS Paint guide on the jump pads in the Veins Of Helios (awesome name by the way). The jump pads are colour coded for the blue and green variants of jump pads.
-The bending arrow in the center takes you to the platform directly above it.
-The arrow pointing to nothing actually points to a walkable construction beam that wasn’t put into the map.
-All distances are based on stepping onto the jump pad without moving or slamming at all.
-The red line shows a tunnel running beneath the main building, with entrances on either side and a hole you can grenade jump through in the middle. Though I believe this requires the Quarantine missions done (may be wrong about that).
