2013's Aliens: Colonial Marines has a list of problems longer and wider than an Alien Queen's birthing canal. But one of the game's biggest problems, its terrible enemy AI, was fixed late last week when a modder zeroed in on—and fixed—a typo that threw a spanner into the works.
In other words, the Aliens' erratic behavior in-game can be blamed on a single deviant letter that clearly burrowed upwards from Hell to torment us all. Colonial Marines' Aliens are supposed to follow a "tether" that makes them behave how a murderous xenomorph should. Instead, the code instructs the big fellows to attach to a teather. Note that extra "a;" it makes all the difference in the world. When the Aliens were handed this set of unclear instructions, they did what most of us do during an existential crisis and flew completely off the handle.
Gearbox, the developers behind Colonial Marines, are understandably a little sheepish about the whole thing. Rest assured the studio is taking steps to make sure it never happens again. A recent job posting for a "programming copy editor" ought to prevent future tragedies like this.
Think you've got the right stuff? Go ahead and apply. Be warned, though: It's a very advanced position, and a "rigorous questionnaire" kicks off the application process. You want my advice? Don't even bother.
