Eye of the Sun quest
You use the turret to shoot at the distant toxic pots. It’s not intended to be mobile.
I tried that. Not able to turn the turret to shot the pods. It is frozen in place. so I can not go any further in the story line.
The turret will automatically rotate to face the area you’re targeting. Put your mouse cursor over the area you want to target with the turret, and hit 1 to fire. The shot arcs a bit, so you might need to adjust your aim point to hit the target.
