The allies had their own set of "super weapons", like radars and proximity fuses. The Nazis had the issue that they wanted to field massive superweapons, but were nowhere near as mechanized as the allies, leading to them being unable to actually practically support those superweapons (and probably also why they went with such over-the-top ideas, hoping that they could do the job with a few units only and relying on scaring and demoralizing the allies into submission).
