Drone Factory

“	Controlled by the Upper Level* test team, deploys a used drone in the Lower Level (drops equipment when shot down).*	”
	—Ancient Ruined Tower description

The Drone Factory is a static device in Arknights, exclusive to Test Site #02 of Defence Protocols, Ancient Ruined Tower.

As with other static units in Multivariate Cooperation, the Drone Factory consists of an upper part and a lower part. The upper player can deploy their units in the adjacent tiles to an upper Drone Factory (marked by a lightning bolt like an L-44 Gramophone's Protocol Entries) to make it generate 1 SP every second per unit, with the friendlies having their DEF halved and more likely to be attacked by enemies. Once the Drone Factory is fully charged, it can be activated by the upper player at the cost of 10 DP to spawn a Cheap Second-hand Drone (Remodeled Second-hand Drone in Challenge Test Mode) on the corresponding lower Drone Factory for the lower player to shoot down and receive Snowsant's Safe Escape Cranes or Mr. Booms from it.
