You Can Fix the Enemy AI in Aliens Colonial Marines for PC by Fixing a Typo

In one of the most bizarre discoveries of recent memory, it turns out you can greatly improve the enemy AI in the PC version of Aliens: Colonial Marines by fixing a typo.

This can all be done with a quick edit in the PecanEngine.ini file. A modder on Moddb explains the process:

A new update will be coming soon with this change included, however after getting reports back from several players on how much this effects the game, I just had to post it now

Inside your games config file (My Document\My Games\Aliens Colonial Marines\PecanGame\Config\PecanEngine.ini) is the following line of code :

ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether -> PecanGame.PecanSeqAct_AttachPawnToTeather

Im sure you’ll notice the spelling mistake

ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether -> PecanGame.PecanSeqAct_AttachPawnToTether

If you fix it to look like the above and then play the game, the difference is pretty crazy!

Why is this line important? There are two reasons :
1) AttachXenoToTeather doesn’t do anything. Its basically empty or stripped
2) AttachPawnToTether does ALOT. It controls tactical position adjustment, patrolling and target zoning

When a Xeno is spawned, it is attached to a zone tether. This zone tells the Xeno what area is its fighting space and where different exits are. In Combat, a Xeno will be forced to switch to a new tether (such as one behind you) so as to flank, or disperse so they aren’t so grouped up etc. (*disclaimer* this is inferred opinion, I cant see the actual code only bits)

Whenever the game tried to do this, nothing happened. Now it does!

So if you fancy a dip back into Aliens: Colonial Marines and own the PC release, you can now play a considerably more challenging version of the game with this quick fix.
