Roadhog is one of the fighters in OverWatch.
His main weapon is like a sawed-off shotgun. That being said, Roadhog is rather useless at long range.
He does have one long-range attack, but I never found it to be that powerful.
You also have a trusty chain which you can pull enemies close to you. The best strategy I found, was to find enemy players attacking your teammates and overwhelming them with brute-force.
His super move turns the shotgun into more of a Gatling gun. While powerful, its accuracy and aim are difficult to master. I never had much luck with it.
But at the end of the day, Roadhog hog is okay, but probably my least favorite so far.
