The bomb I used on my Ultrasonic Bomber ( I thought I might make it more available to the public to have more things to mess around with because I myself like big explosions ) Enjoy. Oh and of course feel free to use it on your creations just give credit. And yes it is a boom 25 but trust me this could crash your game and I tried making my own bomb which kind of worked but the boom 25 was still the detonating part of the bomb and at times failed to fuse resulting in it clipping through the map I couldn't fix this issue I put all my settings up to high etc nothing I did worked. But my previous bomb just looked like the Castle Bravo bomb so pretty underwhelming not the fat man nuke everybody knows so no hard feelings
