Ground Proximity Turrets is an Orbital Care Package reward exclusive to the map Ascend. When activated, four automated turrets will appear on the map. They are slower than Remote Turrets with the Sentry module, but are indestructible.
The Ground Proximity Turrets are not very effective at killing players, as their rate of fire is slow, their target acquisition speed is slow, and Blind Eye users are invisible to the Turrets, being completely able to walk past them. However, the Ground Proximity Turrets can be used somewhat to flush enemies into alternative routes, mainly the underground and side paths, allowing the player's team to lay traps in their wake.
