Roadhog is a ruthless character in Overwatch that loves to cause mayhem. This big guy can take a lot of damage, and dish it out with his shotgun spread Scrap Gun and Chain Hook. His massive health pool of 600 certainly helps him take hits required of a tank.
Roadhog's difficulty isn't that high, but like every character, you'll want to practice to master him. I'm here to give some info on Roadhog as well as some tips to help you play him more effectively.
Roadhog used to be known as Mako Rutledge, before tragedy struck his home in Australia. After the Omnic Crisis, his area was gifted to omnics in hopes that there could be peace between humans and omnics.
Mako and others formed the Australian Liberation Front to fight the the omnic population and take back their home. Things did not go quite as planned and the conflict ended with the destruction of the omnium fusion core. The explosion causes metal wreckage to be scattered everywhere and turned their home into an apocalyptic wasteland.
Mako quickly adapted and wore a mask to deal with the hard environments. He was forever changed by this ordeal and became the Roadhog we see now. There was no more humanity left in him, only a ruthless killer hellbent on destruction.
Roadhog is a tank, which means your main job is to be on the front lines and take damage for your team. You'll want to distract the enemy and keep them from taking out your allies.
That's everything I have for my Overwatch guide on Roadhog. Let me know if you have any questions!
