Okay, now that he'd been shot at and successfully managed to evage, Prompto's brain was starting to switch gears a little, where he was no longer just a bunch of internal flails about being awkward, but starting to settle into the moment. The same way his brain had to switch gears during training, where it took a hot minute before it was less about just spending time with his friends and more about it being go time, there was work to do, this was important.

So he took a moment, while protected by the barricade, to consider the setting, and try to figure out what he next move should be. And this was where he was really wishing Ignis was there with him, because Ignis would know exactly what to do and direct him accordingly, but it was just him this time, so he had to try and think like Ignis.

Blah blah blah cooking, blah blah blah work, blah blah blah when was even the last time you washed that shirt, Prompto...

Okay, thinking like Ignis wasn't going to work, but he figured, if he made his way up to higher ground, he'd have the advantage and could maybe get, if not a good snipe shot in, at least a better lay of the land from above, and he slowly started to make his way there, trying to keep low along to the walls and barriers so he wasn't as exposed before ducking inside the walls.
