I yield on the exoskeleton point, and since, from the way you talked about it, you don't seem too familiar with the term endoskeleton, endoskeleton is simply what us mammals have, as in having our bones on the inside (endo) instead of on the outside (exo)

The fact that they are so susceptible to fire would be quite the liability against Tyranids, who could adapt something to ignite a spark (Don't underestimate the Hive Minds intelligence :3) not to mention the fact that, from what I've seen in the Aliens movies, the Xenos seem to be very much slower than a Tyranid (Most normal size nids, gaunts, warriors, raveners etc) move faster than most guardsmen can even track with their eyes, while the Xenomorphs seem to only be very fast (I am no expert on the Xenomorphs, so I could be wrong here)

I believe that it is a strong material in the Aliens universe, but the Aliens universe doesn't take place 38.000 years in the future, and though humanity has lost alot, they have superior tech to anything we have now. I think Plasteel can stand much but it will be like wearing very heavy cloth against the Tyranids since, as I stated, they can rend through power armor with ease.
