I need help on Soul Trapper when you try to use the soul trap and lock it on to a ghost. I can't seem to trap a ghost because the instructions are a little too unspecific. All it says is "I need to use the soul trap to lock it on to a ghost, then I pull the trigger to suck it in and capture it." It doesn't give any info about swiping or anything.
So I wanted to ask, what do I do?
