Transit

 is a Tier 5 Tank that upgrades from Migrator at level 60.

Design
The has an identical front barrel to Migrator, but its rear barrel is changed to a Director-style barrel, making the tank look something like a Basebrid upgrade. The barrel is noticeably shorter than typical Basebrid spawners though.

Technical
fires blocks whose swarmers have been swapped for drone spawners, now using a barrel arrangement similar to Overseer. These drones naturally hang around the blocks that spawned them until a target steps into their aggro range, in which case they begin pursuing.
