Hmm, sounds like it doesn't have a proper plot other than "advance level"? I'm otherwise all in for some high quality w40k games, but not if it turns out to be some whalebait bullshit.
That game had heavy 40k vibes, almost as if it was developed with that in mind. But that was back in the days when GW did not give out licences like they do nowadays, like candy to everyone and their dog.
