Malcolm seemed to recognize one of the weapons as an early EM type, which also raises the question of what type of power source it used to not run out of juice. Or maybe he was just bullshitting to make conversation.
I always imagined the EM-33, mentioned in Fight or Flight
, as more crude beam weapon. The way the Novan weapons fired gave the illusion of bullets being fired the way we saw only sparks coming off of the cave walls.
But their is no definitive answer one way or the other.
