Gridlock

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

Design
The looks similar to the Necromancer but its spawners are made flatter and closer to the body. Additionally, each spawner gains another identical spawner mounted above it, in a way resembling Uzi.

Technical
Since it has double the spawners, the can spawn sunchips twice as fast.
