As I was inside the FOA2 structure outside the Norrmyra Artillery Base, I had an idea: What if they added a mission where you were to come here and fight some experimental machine, and it would rise up out of the hatch doors that are in the middle of FOA2. You would be stuck inside FOA2 and have to fight it like an arena style fight. This would be the only time you would fight it, and it would be like a boss of sorts.
I was also thinking about how some people have asked for NPCs, but I don’t really think that would fit with the theme of this game. But, what if they had some NPC-types that were like the Terminator, where they were human-like but actually robots you had to fight. The Terminator is from the 80’s as well 
Just throwing some ideas out there
