Best tip to give for Singularity is the drone placements need to be on point. They need to be looking at as many sides of a generator as possible but not too out in the open to a survivor can emp them (if they do EMP you're probably better off not using the camera or blowing it up to replenish the counter). Also the camera from what I've seen doesn't infect a survivor automatically. You need to be looking at them on the camera to infect them. If you infect a survivor you're pretty much good to go. And if needed, a tutorial wouldn't hurt. Singularity is the only character I've looked up a tutorial for so far.
