[DOOM] If Doomguy is from a swords-and-sorcery dimension, why does he easily comprehend firearms and futuristic technology? Also, why is his armor technology-based instead of magical?

Argent D'Nur was not a swords and sorcery dimension. They had advanced armor and what appear to be advanced weaponry. 

If anything they are more advanced that we are. 

But the Doom guy in the new game is *the* Doom Guy from previous iterations. He was born and raised in a society with guns.
