I have made a cheat code where you can change the relationship with the group in Hard Truck Apocalypse (Ex Machina) game. You can enter the following command in cheatmode:
peace(1002) ally(1002) enemy(1002)
You can download it here if you like (for Ex Machina only). The text file contains instruction which is included in the the package file.
I have made a video of Hard Truck Apocalypse game - Cheatmode - War and Peace. This is where you can change the relationship between the groups in the game.
