Engineer-2

 is a Tier 5 Tank that upgrades from Engineer and Builder-2 at level 60.

Design
The has two Engineer turrets on either side of the tank. They each look identical to Engineer, but scaled down to about half normal size.

Technical
Strangely, the blocks all curve to land at the location the cursor was when fired, even though they point in different directions like Auto-turrets. This actually overrides the turrets' aiming, meaning this tank pretty much always shoots towards the mouse.
