I’ve just discovered something major. It makes me wonder if it’s a bug or not!
When Bushwacker’s turret takes too much damage, it emits sparks and thick black smoke for a few seconds. Then it breaks apart.
What I didn’t know was that YOU CAN RECLAIM THE TURRET DAMAGED PAST THE POINT OF NO RETURN. Then you place it nearby. So if instead of setting up crossfire you use it the dumb way, you can have very hard to destroy turret. Most enemies are forced to find another route, they can’t handle the hail of lead, and if you have a teammate for distraction the turret almost never dies.
