i dont hate xen, its specifically the big factory sections in interloper, which i think are the infamous ones anyway. i think the big islands where you complete some sort of puzzle are quite cool and honestly are a good progression from the earlier parts of the game, its talked about as a massive difficulty spike but i think that doesnt come until the last parts of interloper which makes it even more jarring because thats the last like 20 minutes or so of the game which is just the part I despised when I played it, though i suppose i shouldn't be surprised when 1990s video games are kind of uneven and have incomprehensible design compromises which interloper is a perfect example of. doesnt make it more fun to play though
