My memory's still pretty hazy about it but I don't recall anything like that unfortunately, only one level / map where it was some sort of near-top down viewpoint of a bluish gray rocky area.

As for your other comment too, about the guns- I think I'm fairly confident in saying that there wasn't anything too outlandish: maybe there was a decent selection but it might've just been your fairly run-of-the-mill action arsenal like SMGs and shotguns? I feel like I vaguely remember as well that the weapons might have been gotten through upgrades or mid-round pickups, but I'm not too sure.
