Quadral Square

The Quadral Square is a Sentry.

Design
It has a yellow square body and four auto turrets on the sides.

Technical
The Quadral Square has four mounted auto turrets, which have decent firepower (for a sentry).

Spawning
Four Quadral Squares spawn with the Square Sanctuary.

Strategy
There are usually four Quadral Squares that spawn with the Square Sanctuary. Try to get them apart and kill them one by one. It shouldn't be too difficult, as they are usually spawned far apart. Quadral Squares can overwhelm you with pure firepower if you attack them all at once. High DPS tanks or bullet spammers are recommended to take them down.
