Prerequisites
Step
Screenshot
1.) If you are using a PS4 conrtoller, you have to use the DS4Windows Program.[github.com]
2.) Download the latest Nucleus Coop Program[github.com] to play split-screen. (OPTIONAL: Use the 7zip[www.7-zip.org] program to extract, if needed.)
3.) Extract and place the Nucleus Coop files you downloaded in a new folder. (Name that folder anything. I named mine “Nucleus Coop”.)
4.) Place the folder you created into C:/Program File (x86).
5.) Make sure Alien: Colonial Marines is located on the same hard drive as the “Nucleus Coop” folder (in this example, it is C:/). If not, put them on the same hard drive. But do not put the “Nucleus Coop” folder into your Alien: Colonial Marines directory.
6.) Right click on the program, “NucleusCoop.exe”, go to properties, go to the “compatibility” section at the top, check the box marked “Run this program as an administrator”.
How to
Step
Screenshot
1.) Do the prerequisites.
2.) Start “NucleusCoop.exe”.
3.) Click on the “Download Game Scripts” button in the bottom left.
4.) Search for “Alien”. Find “Alien: Colonial Marines”. Click on it, then click “Download”.
5.) It will finish, then pop up with a dialogue. Click yes, then find your Alien: Colonial Marines executable located in “your game directory”/Binaries/Win32/ACM.exe. (You can find “your game directory” by right clicking on the game, then going to manage, then click on browse local files.)
6.) Set up your controllers by clicking on the small box below the keyboard icon. Drag your controllers into your set up configuration. If you have a multi-monitor setup, you can also setup each screen for split-screen here!
8.) Lastly, ingame, with each person, go to Campaign, then Coop Campaign, then press x (or square on a PS4 controller), change Network mode to LAN, then go back and click “Find Game”.
10.) (OPTIONAL STEP: This will reduce startup time) Exit the Nucleus Coop application. Inside the “Nucleus Coop” folder, go into “scripts”, right click on “Halo The Master Chief Collection”, click “edit”, do ctrl+F, find 30, change 30 to 3, and save and exit. Reopen the Nucleus Coop application.
