I think the orange gun is found as dungeon loot unless it is set to 0 in the config. But, I can fire both portals with the default blue gun using the Monster pack. What do you mean by hard difficulty? Which pack are you using?I have crafted the single colored blue portal gun (being in the hard difficulty) I only have the blue portal, I need the orange single colored gun to merge the two into the default gun. I'm asking how do I get the orange gun.
