Musician/sound guy here. Thanks much!
To answer the theme question, the summons you create are the AI you are interacting with. They protect you from attacks as well as go on the offensive. You can also heal your summons via proximity and protect them from the enemy's resurrection device. So there is some simple back-and-forth teamwork there between you and the AI. And, of course, the enemy is also AI, though they are opposition.
Thanks for playing and thanks much for the feedback!
