Teen raging over games

I’m currently at a loss with my 13 year old son. I have 4 kids, ages 13, 10, 8 and 3. My 13 year old has hit a really defiant stage and I’m struggling with handling it. He is addicted to video games and if something goes wrong he screams and rages. When I go in his room to tell him enough and to shut it down, he says no and starts screaming at me to get out of his room and to screw off. Now, my son is huge, 6ft tall 250lbs. I’m 5ft2. I’m not going to “make” him do anything and he knows that. His dad and I are divorced, so on this last incident, I had my parents take him to stay with his dad. His stepfather just feels about done with him because it’s effecting everyone in the house. It scares my younger children. I’m not sure how to bring him back home just to have this happen again. It hurts my heart to send him away from here, but it’s just too much. Any advice on how to handle this?
