Aliens: Colonial Marines: Small Typo made aliens AI stupid
Who remembers Aliens: Colonial Marines (2013) and it's quite horrible in-game AI, as it turns out. The game was borked due to a one letter typo. Deleting the correct letter from a .ini file is enough to play the game, this time with proper AI.
As it turned out, Gearbox Software outsourced a lot of this game to other studios during development and included a “tether” system when assigning AI commands to the game’s enemies. So when you locate PecanEngine.ini in "My Games \ Aliens Colonial Marines \ PecanGame \ Config", as mentioned by jamesdickinson963 from ModDB Ai all of the sudden changes. Change the following:
There only the marked "a" of the following line must be deleted:
ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether
ClassRemapping=PecanGame.PecanSeqAct_AttachPawnToTeather
AttachPawnToTether" controls, among other things, patrolling, the pursuit of prey and tactical position changes. The various zones tell an alien what its surroundings look like and where exits are located. The game is confirmed to show improved behavior.

...I mean that doesn't make it better or understandable...That kind of just makes it worse that there doesn't seem to be any final quality control or you know, someone proofing the code?
Logic-Spend millions making a AAA game, can't pay to have code updated.

This only shows how horrid quality control was made on this title or in Gearbox studio alone for that matter. I'm not surprised that a bug like this slipped through initial code reviews,
but the fact that it was never caught and investigated by dev team is rater astonishing.
I was looking into grabbing this game on one of Steam's sales, but mention of horrid AI in game put me away. I might give it another shot now, on sale o course.

I this actually verified? Spelling errors in ini files usually just reflect spelling errors in identifiers used in actual code. I don't have the game, but someone who does can just do a grep on the binaries for "teather".

so is tether or teather the correct spelling? Tether makes sense, teather isn't a word. I guess the function being called was misspelled so you fix it by also misspelling it in the ini o_O
