I have been trying to hold my breath in the Xbox One version of Alien Isolation. I can not seem to figure it out. Every time I try, the Alien discovers me and pulls me out of the locker (or wherever I'm hiding). So two questions: A) How do I actually do it (hold my breath) B) Is there some sort of visual indicator showing that I am holding my breath?
I'm not sure about the Xbox One version, but the PC version using an Xbox 360 pad has you hold your breath by pressing and holding LT (left trigger).
HOWEVER, you also need to be leaning away from the door (down on the left control stick) or the Alien will see you.
After you've been holding your breath for a bit, the sides of the screen will start to flash red and you'll start slowly taking damage (I think). At this point, you also start making a small amount of noise. From experience, you will remain trying to hold your breath until you let go of both LT and the control stick... and hope the Alien hasn't heard you.
I die most of the time. But I managed to survive twice.
It'll either prompt Push the LS (Left Stick: push down on the stick) or LT (Left Trigger) Button. Hitting either button before doesn't do anything.
For it to work I think you need to be in a neutral position (not already leaning back) when it prompts.
So when the text appears push one of the two button, then lean back. Hold it until the Alien is far enough then release. You'll see red flashes on your screen when holding your breath.
On the xbone version you have to pull back on the left stick and hold the left trigger at the same time. Don't pull LT until the enemy is close.
You're fine at first, but the longer you hold your breath the more a dark red effect spreads in from the edges of the screen.
When you finally let go you'll make a quiet noise and see flecks on the edges of your vision.
