Experience Aliens: Colonial Marines how it should have been when it first released. This mod includes fixes to AI, textures, balancing and more.

Report RSS The biggest BUG in the game is just one letter long

A typo found in the INI file after all this time appears to be one of the major causes for terrible AI mechanics in the game. Thankfully typo's are easy to fix!

Posted by on

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) AttachXenoToTether 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!

Was this typo made by you or Gearbox?

This is up there with the infamous Beregost crash in Baldur's Gate where a single open door was the cause.

So suddenly the Xenos are more aggressive and overall more swarmy?

Not so much more aggressive. They are much better and approaching you without getting shot. They will move between cover more, and if you try shooting them, they flank and displace

So correcting this typo, combined with the AI enhancements you've already made. Would this make the AI of both the Xenomorphs AND PMCs even better????

The Xeno's are insane now. unfortunately they do still stand still at times. But its much rarer than it was.

They run around on the walls and roof alot more now and jump ontop/over tables and cabinets more making it much more difficult to deal with multiple of them.

The Humans don't benefit from the typo, but they are better than before mainly in that they have more freedom to get into cover and think faster. W.Y have very low health to make them easy to take out (except for a heavy) so most fights with them can be dealt with quickly.

In missions where its a mix of Xenos and Mercs the Xenos clearly dominate just about all encounters

I saw another post about another typo from geoffegg so thought copy paste it here. I believe we are all still missing this second INI fix that needed still.

This typo is in the DefaultEngine.ini, in your Steam\steamapps\common\Aliens Colonial Marines\PecanGame\Config\ directory

Turns out the biggest bug in the game isn't just one letter long Templar, it's one letter wrong too.

I've found out ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether also has a typo on the exact same line as the AttachPawnToTeather typo. It says ClassRemapping=PecanGAme with a capital A in Game which could potentially be causing a problem as well. (lower the A to "a" yes)

This exists in the DefaultEngine ini file, which is what serves as a default for the PecanEngine config in My Documents.

Just been testing it out quickly with both typo corrections in the Vanilla ACM and it looks to me like the Xeno Soldier's are definitely wall and ceiling climbing more, only tested No Hope in Hadley's so far.

Hey all,
My name is Sean Maio. I was one of the three Colonial Marine cosplayers (the Smartgunner, specifically) who SEGA hired to be their booth characters, mascots, etc for the A:CM booth at E3 and similar shows. The three of us are actually featured in the game in mission 9 as some of the Marines you rescue when you return to Ops - look for "A. Duplis", "C. Duplis", and "Maio", respectively. That's us. You can also find our faces in the multiplayer appearance options.

One result of the promo work we did with SEGA was that I ended up getting flown to Gearbox to do Motion Capture work for the game - their first try MoCapping the Smartgun didn't work out so well and they needed my rig. While I was there, I got to meet the devs, playtest development builds, give feedback, etc. Believe me when I say, from firsthand experience, that what I saw in development (pre-Timegate) was much closer to the E3 demos than what actually ended up shipping.

For years, I have been trying to understand the difference between what I saw and what shipped. This. Explains. So. Damn. Much.

Anyway, I just wanted to share this story with you all and tell you how much it warms my heart that there are still people who haven't given up on this title despite all the drama, and are still trying to polish it into what it could have been. The Gearbox devs who worked on this pre-outsource were so freaking passionate about "Pecan", and I know they would feel the same way. Y'all stay frosty.

Thank you Sean, for this positive feedback for us real legit ACM fans to read! I've been playing since day one release very underrated and awesome. I didn't care about the hate bandwagons still today after all off this reporting from PC Gamer they never will be happy!

Mission 9 really loved walking around Hadley's Hope. All three off you were all meant to be pulled into the vehicle bay area as you all had lines throughout. Both you and C.Duplis You have to force push trick you all in but can only be done in coop.

Anyways for us real ACM fans because why should we be bullied for liking this? I spoken to many online they all loved playing coop, Bug Hunt Mode and all four multiplayer modes.

Online is still very active on the PS3, 360 and Steam today on July 2018. We got to customize a male and female marine so again thanks to your efforts.

Hope everyone can keep on supporting this for a future remaster on current gen.

Fun fact, my head was originally supposed to be attached to the generic Smartgunner body (the ones you occasionally see running through the docking tube in the title screen) as an homage to my actual costume. They never told us we were supposed to have lines, though.

At the end of the MoCap session, they actually asked me if I wanted to survive in the game or not, lol. We recorded three different death options - one where I got facehuggered, one where I went down shooting while getting mobbed from multiple directions, and my favorite, one where I got a tail through the back. I told them to surprise me.

There's some fun behind the scenes stuff in this YouTube vid from PAX (skip to around 8:30 or so) - Youtu.be

I've also got some pics I'd be happy to share if y'all are interested. Regardless of the outcome, getting to work on this project was a fan's dream come true and one of the best experiences of my entire life.

You wouldn't be surprised all those death animations were all used ingame. Hey we all rescued you off that floor yeah you in a Aliens game forever. Who can that away from you.

Maybe Hiya Toys could make a figurine off you as they have the ACM licensing ah maybe not your likeness rights. They should be releasing The Crusher, Raven, Cruz, Redding and Bella figurines by now. They be at San Diego Comic Con this coming week said on there Facebook who knows until then.

What PC Gamer and the fifth person on Twitter are NOT telling you is Templargfx real research with the Overhaul Mod. The game like all games fellows scripts so the Xenos, Wey-Yu PMCs and your fellowing parents all have to fellow some script before they are "free" throughout the two campaigns.

The two INI fixs correct the AI to be able attck you from everywhere. End of the day the game isn't "unlocked". By unlocked meaning the console limitations yes the PC version was locked out to be at its fullest like you can get now with V5. As the game was only built on a 512mb RAM kit old one at that!

The Overhaul Mod unlocks pass these consoles limits then some to the heights off 4k gaming today! Yeah the cut scenes are not in 4k nor even 1080p but the ingame yes stunning! Now the old gen consoles are still stuck with the typos and yes the console limits itself.

A full support and backing would help for a current gen release. If you hate the game because wasn't what you wanted okay fine. For us who have enjoyed this well Oorah To Ashes!

By the way - as a result of learning about this AI fix I'm now planning an *IN-COSTUME* A:CM "vindication" playthrough on Twitch, lol, so if that's something y'all would be interested in, spread the word.

To be honest - it took me like 10 minutes to pinpoint this typo EVEN you explicitly showed the specific line. And I code daily. It speaks more about evils of external string literals than anything.

I'm glad post author found it but I don't think it's a prudent idea to hold this particular mistake against the developer; many games we love is full of similar ones - this one was just extra unfortunate.

Basically it means there non-declared function was called.

It seems it was ad hoc created as an empty do-nothing stub.

....and for 4 years that was not written to any error or warnings log. :-/

Something I mentioned elsewhere. I spent 3 years working on this mod before I found the typo, every gamer/modder that played ACM messed with those INI files. No one saw it, not a single gamer for what, 4 years?

4 years of rabid Aliens fans like myself with coding knowledge missing it kind of says you can't really be too hard on the Devs for missing it too.

Hi all, was looking in the default engine INI and found that +Suppress=DevDialogue has +Suppress=DevDialog added underneath, which seemed odd to me. So I deleted the line and closed the gap, then ran my game. Suffice to say it ran fine without it.
Obviously I will replace it if it was wrong to remove, but it didn't make any sense to have two commands for the same thing...

I've ranted abit about that too on here about the sabotage. The Gamer Media was showing us E3 demos, Gifs (Boilers Are Blind, you know can get a achievement if you stop those Xenos from jumping over that blockade?) and promo artwork to put off potential newcomers playing the game. Those PC Gamer "tether" gifs was insulting!

I'm sure all those E-celebritys never bothered to watch James Cameron Aliens at all. They claim too love the "second movie" oh no "ACM is too much like Call Of Duty, Halo, Mass Effect, Dead Space, Gears Of Wars".

Well yeah the United States Colonial Marines Corps are just as tech and weapon heavy. That was the whole point to Private William Hudson dropship showmanship of being the "Ultimate Badass'.

I hate to bring up certain media articles and YouTubers been some unreal researching. If only resetera and PC Gamer just saw that second typo below we would had Two instead One typo articles past week. No mention about poor Weyland-Yutani Commandos getting the added benefits with the typos!

I will leave PCGamingWiki ACM guide here great they included both typos.

Agreed, I doubt they even get any of the small in game movie references, like Ripley's X-ray on the walls of the labs for example. It just seems easier to pander the same old tripe for the audience and gain more subs.

Night and Day here just refreshing to read real talk about the game new light. I will post them up.

4Chan - They closed down every thread about this game past week. Odd.

AvPGalaxy - I was about to sign up tell them you know about these other typos right...toxic thread shamed to be Aliens fan there.

BBC - Play Fortnite instead. Posted some twitter post saying "still very bad" good reporting.

Gamespot - N/A

IGN - That Ryan Boss man who says he played on this on the Xbox 360. Why haven't you played the PC version yet? Good reporting again.

AI and Games (YouTube) - I watch this video I couldn't believe this guy was downplaying the overhaul mod to his viewers! "only improves the graphics". His love for Isolation was way too much for me had to stop watching.

Kotaku - "Still very bad" Yeah right.

PC Gamer - Yeah odd they didn't noticed that other defaultengine.ini typo...sure they knew.

Too much cut this short.
