Well, I think it's a thermite and nuclear bomb, not too sure what to call it. I'm kinda new to this game so yeah here it is. All you have to hit is space and it resumes. :)
I have made a bomb similar to this. Thermite was on the outside, and the fissile elements (DEUT and PLUT) were triggered by THDR in the center. This shot molten thermite everywhere. REALLY HOT molten thermite.
