To protect spawn points I recommend something like this
You can look at it like a side objec that protect the Spawn aera from enemies campers.
Its an fixed auto turret where you (SD) can put any where (top buildings high /low )
But the switch to activated/repair can be place at ground level or in a room etc…
With a High health/shield/damage porperties that can be damaged/desactivated and repairable should push ennemies away from spawn aeras
You can also place some in other aeras where the switch could be more at risk position (harder to activated due to be on ennemies sight) and lower the turret properties (health/shield/damage)
Turrets can anything you wish to do ( bullets,laser,rocket)
One turret in WC garage (1st object) could be handy , this switch could be place in a riskier zone
