14 Video Games You Should Never EVER Play

9. Aliens: Colonial Marines

Gearbox Software worked on Colonial Marines for over six years. (If that sounds like a long time, it is same company that made Duke Nukem Forever).

Every aspect of the game was torn apart; low resolution, uncreative gameplay, technical issues, etc. It was so bad, the developers got sued for false advertising after they released a demo that gave the impression it was... y'know... a game.

But what it's infamous for is the atrocious enemy AI. Colonial Marines' reputation was irreparably destroyed after a video went viral showing a Xenomorph in the game casually walking by the player without attacking him.

Although Colonial Marines's inept AI is well-known among gamers, most people don't know why it happened.

The answer to this mystery is one of the scariest words in the gaming industry; code. The Xenomorphs are programmed with a tether system so they hunt and destroy any player in their vicinity.

So why didn't it work? Because the programmer misspelt the word "tether" as "teather". When a player approached a Xenomorph, a misspelt code activated, causing the alien to do nothing.

So, there you go. The entire game was destroyed by a single letter.
