A gravity cloud would so much more usefull.
We should have a test-unit to initialise our first Newton and inherit the calibration on other Newton turrets.
This test unit is invisibly spawned above Newton and get attacked a fixed time.
Once it doesn't fly away too slow/fast we have a calibration value for Newton - have every time the same "map gravity".
If we have an Elevator unit, we could give it load and unload zones.
It should pick up units from it's load zone and throw it in the right direction and arcing to the unload zone.
