the Hover Spear.
This bulky unit will block most of Hover's direct fire weaponry, but aims to ensure that Hover units can keep distance with enemy units. It's a slow moving fixed weapons platform that can only fire it's gravity cannons in a narrow forward arc to repel enemy units. It must turn to face whatever it fires at. In a battle sense, spears are meant to deal with sword welders by keeping them at range with their long spear rods.
The forward arc makes this unit unable to do much of anything against planes or units on hills. It's best on the flat plane or the open water.
Note: the spammy archer thing has legit ingame physics problems, like permalocking a goliath in place.
