Occupier

 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 split into two tapering barrels that look like swarming barrels.

Technical
fires strange octagonal blocks that do not really correspond to any Cruiser upgrade. Each side of these blocks has a small spawner, allowing the blocks to spam small, weak swarms very fast.
