Azrael the cat
Arcane
Then, it is another Penumbra...
Nah, it's more than that, just not combat focused. Perhaps you can combat androids or crazies, we don't know yet.
I don't know that I'd trust a modern gaming company to pull this off, but I'd love it if combat was treated as something you might occasionally do depending on what comes up from character interaction, rather than mowing down mooks, as in Azrael's Tear. Smallish initial crew, some with conflicting motivations (but not necessarily villainish per se), then partway through a military team turn up - keep combat small-scale, and in the context of 'I'm killing this particular guy', not 'I'm killing so many random dudes that any sane moral caclulus would conclude that it would be better if the 1st guy had just capped me straight up'.
In any event, if they wanted to include combat, there's plenty of other enemies they could use while keeping the alien unchallengeable.
