[Spoilers] Does completing the TIS puzzles reveal any additional plot points?

[Virgil]

I don't care about the puzzle concept itself compared to the regular gameplay but I'm curious if you get hidden story details.

Do we ever find out what happened to Nathan Trucks?

Spoiler 1: As far as I can tell, the TIS puzzles just provide a bit of flavour text. You don't get a new ending or anything for having completed all of them.

Spoiler 2: Trucks' fate is never explicitly detailed. If I recall correctly, does he go off on his own before or after the SADM is used? If before, his fate is pretty clear (he's radioactive debris). If after, well, it probably doesn't end well for him.

As much as I would love to see this game get some more content or even a sequel, I doubt that's happening. It looks like the developers are done with this title and aren't planning to release anything new for it, not even modding tools.

Trucks... After the missions where you retrieve all the trucks (trucks... ha) full of enemy VIPs, DeMarco sees a doppelganger of himself, who's an enemy officer, implying that alternate versions of people exist in the parallel earth

After the guys get back and are decontaminating, one of them mentions he keeps seeing a guy he thinks is Trucks, but it's not him

My theory: Trucks (our Trucks, the psycho Vietnam vet with a Death Wish) went AWOL and stayed on parallel earth, because fighting is all he knows. Fighting against the parallel Americans or helping them against the ISROs, we can only guess. Maybe he found his alternate version and decided to give him a chance at life on safe Earth... but this would seem out of character for him, considering he believes might makes right
