Essential improvements

ACM Overhaul

Comprehensive overhaul mod that fixes AI, balancing, textures, and more.
ACM Overhaul does not contain all possible graphic corrections and corrections in aliens AI. If you want such fixes, download this file.
Changelog

Skip intro videos

Edit PecanEngine.ini[2]
  1. Edit %USERPROFILE%\Documents\My Games\Aliens Colonial Marines\PecanGame\Config\PecanEngine.ini
  2. Change each instance of StartupMovies= to //StartupMovies=
  3. Save your changes and close the file.

Another method is to simply edit your shortcut target and add a space at the end of the path, followed by -nomovie. This has the advantage of also bypassing the legal screen as well. Note, however that this method will also skip the in-game intro movies.

Improved Xenomorph AI

This results in improved wall and ceiling climbing for the xenomorphs.
The fix is also included in ACM Overhaul.
Edit two spelling mistakes on a line in DefaultEngine.ini[3]
  1. Edit <path-to-game>\PecanGame\Config\DefaultEngine.ini
  2. Find
    ClassRemapping=PecanGAme.PecanSeqAct_AttachXenoToTether -> PecanGame.PecanSeqAct_AttachPawnToTeather
    and change it to
    ClassRemapping=PecanGame.PecanSeqAct_AttachXenoToTether -> PecanGame.PecanSeqAct_AttachPawnToTether
  3. Save your changes and close the file.

Notes

The config line includes two spelling mistakes that the above fixes:
  • PecanGAme instead of PecanGame
  • AttachPawnToTeather instead of AttachPawnToTether

Issues fixed

Failed to start game (app already running) error

There is no universal fix, however these are confirmed to work for some users.
Delete appcache folder[4]
  1. Go to the Steam installation folder.
  2. Delete the appcache folder.
  3. Restart Steam, game should update itself.
Set Steam language to the same language as the game[5]
If that does not work, try changing also operating system language[6]

Failed to start game (RU release doesn't work when English language is selected)

This solution is probably applicable to other non-English releases.
The game crashes to desktop after trademark screen, shows one of the error messages from previous issues.
Copy INT folders from Russian version[7]
  1. Set game language to Russian (within Steam select game Properties -> Language -> Русский(Russian))
  2. Wait until the game download localization files.
  3. Locate <path-to-game>\PecanGame\Localization and <path-to-game>\Engine\Localization folders and copy their contents somewhere safe (You need only INT subfolders, they contain different files, don't mix them up!).
  4. Set game language to English.
  5. Wait until the game chop it's legs off (it removes said INT folders needed for game to function).
  6. Copy both INT subfolders you saved earlier back to <path-to-game>\PecanGame\Localization and <path-to-game>\Engine\Localization accordingly.

Blue screen on AMD CPU

There seems to be problem with game running on AMD FX processors where game crashes to BSOD or freezes system. Issue is similar to Borderlands 2 BSOD and fix also works with Aliens: Colonial Marines.
Update BIOS[8]
Addition information and links to motherboards websites can be found at AMD knowledge base library.
Update procedure varies and can cause motherboard to malfunction when update is interrupted or applied incorrectly. Read carefully manual to your motherboard and instructions on screen when updating.
Information about Borderlands 2 BSOD issue can be found at Gearbox Software Support page.

No textures

Forcing anti-aliasing via drivers on Nvidia GeForce cards will result in missing textures and black game scene.
Disable anti-aliasing in graphics adapter[9]

Game Freezes / Crashes during Session

Due a memory restriction (x86 build), the game is limited to work with a maximum of 2GB of VRAM. Try either:
Lower V-ram intensive graphics settings such as Resolution[10]
Play in Full Window mode instead of Fullscreen[10]

GPU detection fix

Game has problems with detecting some graphic adapters - mainly mobile GPUs and new graphics. Because of this, game can select wrong settings profile for your system.
1. Checking GPU detection[11]
  1. Open %USERPROFILE%\Documents\My Games\Aliens Colonial Marines\PecanGame\Logs\Launch.log.
  2. Locate line [0000.53] Log: Machine detected compatibility level: Composite: X. CPU: Y. GPU: Z. where X,Y and Z values are assigned grade of your system. Value of 5 is the highest grade for high end hardware.
  • If you've got powerful hardware and you're not getting high enough grades, follow the guide in the next fixbox. Otherwise you don't need to change anything.
2. Adding your GPU to the hardware list[11]
  1. In file Launch.log locate these lines:
    [0000.53] Log: GPU stats:
    [0000.53] Log: 	VendorID: 0000YYYY
    [0000.53] Log: 	DeviceID: 0000XXXX
    [0000.53] Log: 	DriverVersion: <numbers>
    [0000.53] Log: 	DeviceName: <GPU name>
    
  2. Edit %USERPROFILE%\Documents\My Games\Aliens Colonial Marines\PecanGame\Config\PecanCompat.ini
  3. Locate section for your vendor - search for VendorName= value.
  4. Add line into your vendor section for your graphics adapter. Use information from Launch.log file like so: 0xYYYY=G,<GPU name>
    where:
    YYYY        -  last four digits from VendorID
    G           -  your desired hardware grade - 1 lowest, 5 highest
    <GPU name>  -  string from DeviceName
    • Example 1:
    [0000.52] Log: GPU stats:
    [0000.52] Log: DeviceID: 00001244 
    [0000.52] Log: DeviceName: NVIDIA GeForce GTX 550 Ti

    will result in 0x1244=5,NVIDIA GeForce GTX 550 Ti

    • Example 2:
    [0000.53] Log: GPU stats:
    [0000.53] Log: 	VendorID: 00001002
    [0000.53] Log: 	DeviceID: 00006738
    [0000.53] Log: 	DriverVersion: 8.17.10.1169
    [0000.53] Log: 	DeviceName: AMD Radeon HD 6800 Series
    will result in 0x6738=5,AMD Radeon HD 6800 Series
3. Additional graphic enhancement for high-end hardware[11]
This step is optional. It will force maximum quality level of detail for grade 5 hardware.
  1. Edit %USERPROFILE%\Documents\My Games\Aliens Colonial Marines\PecanGame\Config\PecanCompat.ini
  2. In section [AppCompatBucket5] search for these lines:
    TEXTUREGROUP_World=(LODBias=1)
    TEXTUREGROUP_WorldNormalMap=(LODBias=1)
    TEXTUREGROUP_WorldSpecular=(LODBias=1)
  3. Change ones to zeros and save the file. Additionally you can tweak some other options in this section.

No weapon

Switch between weapons[12]

Unresponsive controls

Problem with controls where in-game camera is always rotating and in menu cursor is always moving down. Demonstrated here.
Unplug all USB game controllers, alternatively disable them in Device manager[13]
.ini edit[13]
  1. Open %USERPROFILE%\Documents\My Games\Aliens Colonial Marines\PecanGame\Config\PecanEngine.ini
  2. Locate line AllowJoystickInput=1 in [WinDrv.WindowsClient] section and change 1 to 0.

Notes

  1. 1.0 1.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/49540/ in addition to or instead of this directory. The app ID (49540) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
