up at the top section of the map at the first house behind the short wall facing the trail
On the Phantom Unit side, near the staircase there is a tiny room near the exterior staircase. If you find that, place the turret facing the wall (It's seems wierd but the turret actually shoot thru the building and all the enemies that come down from the top section of the map).
At the KPR main starting position spawn, there is a small hut/building. Near it there is a small trail. If you go there and place the turret facing the spawn it will be camouflaged by grass making it virtually impossible to find.
At the Phantom Unit spawn there is a big building with a white interior staircase. Go up on it and you will find like a snooker table thing. Place the turret facing through one of the windows(Doesn't matter which one). All enemies rushing outside would be killed unless the enemy has armour elite.
At the starting position spawn of the Phantom Unit place the turret beneath the staircase. Almost all enemies would be killed as by the time they come down the staircase the enemy would be at like 10% health. Unless of course the enemy had athlete elite or camouflage.
Place at or near KPR spawn. This tactic wouldn't work if the KPR team had high rank players. They'd probably know where you placed it.
On the outside open air section of the map, go on up the staircase. Walk towards the part of the map that isn't near black staircase. There are 2 white staircases. Place the turret on the side like a 'flanking' side. If you do this, all enemies running up the stairs would be killed.
At the outer section of the map on the top part. Place the turret under the staircase (KPR Side).
At the phantom unit main spawn, place the turret near the boxes facing the staircases. Works very well as the turret shoots through the lower walls.
At KPR Spawn there is a small group of boxes. Place it in such a way that it looks camouflaged by the shadows. Works very well as people tend to sprint into the rooms (and when you sprint there is a slight blurry effect on the sides. Which means there is a low possibility of you spotting the turret. Unless you're looking directly at it shooting you).
At the right side of the map (KPR side spawn POV), there is a wierd blown up section of a wall. The floor looks muddy and the entire space has a shadow over it. Place the turret in the darkest corner. Works very well unless playing with high-ranked players.
On the top side of the map, there is a like a rock with a small gap. Placing the turret there facing the rock itself at not the gap, will result in a lot of kills. The turret doesn't shoot through the rock, the rock is low enough for the gun of the turret to poke out. Strangly if you look at the rock from a distance you cannot make out its there.
