You may want to make the research of an alien Navigator prerequisite also accept an Aquatoid Navigator in addition to Lobster Man and Freak(which I never encountered)
No, it will be too easy.
BTW I had 5 or 6 missions (4-5 cultist raids and 1 terror) that took place on the "cargo ship" map with completely the same layout. Dunno if that was intended.
Yes, it is normal. Cultists do not interested in hostages, only silent robbery of cargo ships. And aliens - just random.
Upate 1.03 is here.
Changelog:
- fixed live alien recovery (third try, including naga, polyph and freak);
- fixed broken ufopedia articles: sonic tech, alien cruise;
- slightly nerfed gas cannon ap ammo and buffed supercavity harpoons;
