According to the in-game News feed, it would appear that Mounted Turrets will be heading to Fortnite in the next update. The description for the item reads: “Place the Mounted Turret and hop in to apply some suppressive fire! Careful not to overhead”
This would suggest that the Mounted Turret will be an item that you can pick up and carry around, and then can drop it into your desired location when you want to put it to use. From the description, it’s clear that you’ll have to control the turret yourself, rather than it being any kind of AI-controlled death machine like the Sentry Turret from Call of Duty. The description also suggests that the weapon will overheat through continual use, which should hopefully help to keep the item balanced.
A lot of players are worried that the turret may be overpowered, but I’m not so sure. On the one hand, fighting a turret head on will lead to almost-certain death, but the overheating mechanic—coupled with the fact that people who sit in the turret will be sitting ducks—will hopefully keep the weapon balanced.
There has been no official date for when the Mounted Turret will be introduced into the game, but we can probably expect it as part of the next weekly update, which should arrive in the next couple of days.
