You'd need to atomize it, since that's just to counter it's regen per second and while nuking it will do a fair bit of damage, you've got to nuke it again in time before it's regrown what was vaporized with the last one. They instinctively hunt in packs too. And have obsene reaction times. (Even for Nids.) So it could likely see the nuke and outrun the worst of the damage. I think you'd have to use a ships lance batteries on it or something.
What exactly is one of those bio-titans' top speed that lets it outrun a 410th century nuclear bomb? And are you treating its regenerative capacity in some manner that involves "hit points"? Because I doubt any living organism of that size could survive one of these: View: https://www.youtube.com/watch?v=gvcY9Nh_rlQ The shockwave should tear it apart. The heat should scorch it to a crisp. The radiation should vaporize a radius around the device. Etc. These things destroy entire cities, and somehow a giant insectoid survives one? I call BS.
The last twenty mins alone are about explaining how the hierophant would work IRL. Most just got a 5-10mins. Edit: After listening to that, i did make mistakes, been awhile since I've listened to t.
It eats it, becoming the nuclear bomb. Therfore being able to withstand a nuclear bomb, but blowing up as a side effect.
Um. I'm imagining a nuclear bomb with the mass of a Tyranid bio-titan. Did anyone manage to get off-world in time?
