Research question

Now i may be wrong, but i do believe that in the original x-com research wasn't shared between bases, like each one was standalone. Will this be implemented also in Xenonauts at any point? or will research just be global and shared?

research just be global and shared

This

Yup, research is global and shared, manufacturing is base-specific.

This makes quite a bit of sense - why shouldn't research across bases be collaborative?

I'll probably miss having to build a monster research base above the Arctic circle and keep it hidden from the alien hordes though.

No reason not to though

It'd be nice to have the aliens go after your internets, slowing research. could also make a nifty objective based combat map. "No explosives, we need those servers up and running!"

The aliens can damage most rooms in base attack missions by blowing up the props inside them. At worst, this will set them to 0% construction so they'll have to be rebuilt from scratch (albeit for free), but they can't be used in the meantime.
