it would have been awesome if you were able to take the gun and rex to dr. h and had him combine the two in order to give rex a ranged attack! what do u think? it was the first thing i thought when i saw that there was a cyberdog gun in the dlc. i know dlcs arent supposed to interact with the main game,but still, the cyberdogs in the dlc had ranged attacks. rex needs a brain and the gun has one, seems likely you should be able to combine them. maybe bring rex to the splicing facility, and splice them together. i think it would have made it a much more interesting story.

Dlc's are independent from each other and can't interact with the main game and each other. But I agree that it would have been cool

It would have been cooler to turn Roxie into a Cyberdog Gun. That's what would have been cool. The gun would be named "Lady", in reference to Lady and the Tramp. :3
