Here is how he dies in this edit.
Han is planting the bombs to blow up the facility. Kylo walks out onto the catwalk, turns around, and says “Han Solo. I’ve been waiting for this day for a long time.” We cut to Han placing a bomb. Kylo says “I’ll show you the Dark Side.” Quick cut to his gloved hand extending. The bomb explodes and Han goes along with it. Kylo takes off his helmet, we cut to Leia feeling Han’s death, and then we cut back to Chewie gettin’ pissed and shooting everyone.
