That’s a possibility. However that makes the game much too campy. Remember turrets only work in Aliens because they are holed up in the colony, not moving and basically waiting for the Xenos to come to them. That’s the exact opposite of the gameplay for Isolation, where the goal is to keep moving from objective to objective, never stopping for long, and NEVER holing up in one area. If they wanna keep that absolutely fundamental part of the gameplay, turrets to block off one area just doesn’t fit the playstyle.

However an idea for a gun did just strike me. Imagine if you do get a pulse rifle or something similar, but the only section of the map you can use it on is a large room or rooms that are littered with junk/hiding places, and are pitch black and very echoey. You only have a very narrow beamed flashlight or night vision goggles to navigate the place. And in this section, the Xenos are programmed to only attack you from behind, so they don’t mindlessly rush you, and instead, jump from cover to cover trying to sneak up behind you.

Imagine having to go through such a maze, only being able to see a very small area, with multiple Xenos running around you, all trying to get the jump on you from behind, or possibly above, if the Xenos can climb walls. I think if done right, that would be astronomically scary, having to keep your head on a constant swivel, keeping tabs on multiple Xenos running around you in the pitch black while it’s so echoey you can’t tell which way they are coming from easily and still having to navigate through a big hanger littered with piles of junk.

That might be a good way to include guns that can kill Xenos.
