This one's actually my favourite. so, I'm going to put extra effort in explaining this one. I've been a fan of the ALIEN movies. so, naturally the games became my favourite too. one really terrifying feature of this game is that in Alien: Isolation the xenomorphs can pick up sound from your mic, and if you're too loud, the Alien has a better chance of finding you – wicked 🖤
