Overseer

The Overseer is a Tier 2 tank that can be selected starting at level 30.

Design
The Overseer has a circular base, with one trapezoid on each side of it.

Strategy
Staying at the very corner and sending out your minions via alt fire can reward points from far away. However, when doing this take in mind that an Overseer without its minions is helpless.

Great tank for playing normal mode in teams as you can protect teammates, and you're very unlikely to accidentally hit them.

When attacking, going for tanks with low rate of fire is the plan. Tanks with higher RoF can defeat the minions while running away.
