I understand why it was put there and it does make sense for a big creature. The other thing that was annoying were the loud footsteps. I really enjoy this mod, I believe it has a nice balance. It feels like he is more unpredictable now. I see him less but when I do it's because I got careless and it feels like a surprise more and then I die of course. Now this feels a lot more realistic to me.
Lets him explore a lot more further and drops down a bit less frequently without making him less aware and aggressive than he is when playing on Nightmare. The solution for me was the Unpredictable Alien mod that unchains the invisible leash the Alien has to the player. I keep thinking if he knows I'm there, how is he not finding me? Doesn't make too much sense to me. But it was always weird to me how the alien just drops down from the vents a lot more frequently and stays in the room you're hiding in a lot longer, yet wont find you if you hid well. I play on nightmare whenever I'm not playing the Survivor missions and it's great feeling. I'm mostly interested in the mods that make the game harder, yet not unrealistically so. I've been playing the game for a long time now and I truly believe it's one of the best Alien experiences out there.
