Aliens: Colonial Marines was released in 2013 and was met with some really terrible reviews. In the game, your enemies, the aliens, sort of shuffle around like you aren’t there, making for some pretty lame gameplay. The cause of this is actually a typo in the game’s coding.
Australian modder James Dickerson discovered the error in 2017 while working on an overhaul of the game. He found this line of code:
ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether -> PecanGame.PecanSeqAct_AttachPawnToTeather
Look closely. At the end of the code, “tether” is spelled as “teather,” causing the AI for the aliens to ignore the player and not know when or how to engage.
Luckily for anyone who still happens to have a PC copy of this originally horrendous game, you can fix this code! Dickerson’s explanation of the bug, how the code works, and how to fix it can be found here.
