It's a wild guess but maybe it's to attach other bases to make a giant city.

Doubtful. The way the gun pegs onto the leg, leaves the slot pretty inaccessible to everything you would want to connect there. And using the hinge clip to attach it to anything else, means you can't really use the side peg to attach it to Fortress Maximus. There's just no way I can see for that gun to serve as a city extender. Even in that picture, I don't believe its using the back slot to attach to Astrotrain, more than its just resting there.
I believe it can attach onto the back of Blaster and by extension Soundwave, but why you would want to do that, I'm not sure.
Might be a feature that was scrapped before release.
