I am not basing it on either Xenonauts nor XCOM.
I am basing it upon the real life examples.
- Modern day bullet resistant vests use ceramic plates.
- The Space shuttle uses thermally resistant insulation plates of Ceramic.
- Rocket nozzles are sometimes covered in ceramic material.
The fact of the matter is, I am betting that we use ceramic plates now for our armor.
the post i made earlier is just incorporating alien alloys into it, instead of using extremely expensive alien alloy plates everywhere. Ideally, it would be cheaper then a straight alien alloy armor because it is using less in terms of otherwise prohibitively expensive alien alloys.
Another point i want to make is the fact sticking exactly to what happens in the game is honestly boring, Yes we can use Elerium and yes we can manipulate alien electronics and alloys for several things, but were not doing it in a easy way. Making straight alien alloy for our armor using methods that should honestly be reserved for vehicle equipment right now (due to its expense) when we have the option of presumably committing the same or similar amount or protection with a cheaper method points wise that would allow us to spend our industrial capacity on other, cooler assets should be considered.
I can understand if we're going for the equivalent of a plate carrier of alien alloys along with a helmet and then some miscellaneous features, but the Xeno-Ceramic armor would allow to do more extensive protection over more of the body cheaper, as it allows the use of more (and less immediately changeable) alloys in its construction, rather then only the alloys which we have the ability to manipulate (assuming that we cannot manipulate some alloys just as easily as others.) It may even be possible to have it become a standard among our forces, as it could use surplus alien alloys in the production of the ceramics in a cost effective manner.
Yes, we can make alien alloy armor plates, but we could also make xeno-ceramics that could be more comprehensive, less resource intensive, and would give us experience in making actual armor for personnel instead of diving into a relatively new field.
