This is one of the most bizarre stories I’ve read and subsequently written.
Alian: Colonial Marines had a lot of issues, but one of the major ones was that the Alien’s A.I was pretty bad (which is a fundamental part of creating these games).
Well, after five years, one modder has discovered that fixing a typo, has majorly improved the A.I. Apparently a key piece of code, spells the word ‘Tether’ as ‘Teather’ and this is directly related to being chased by the Alien. It’s a pretty big deal and is explained in detail below.
