If you're not familiar with the game it's basically fly an AC-130 and shoot zombies. Simple enough, and it's usually those types of games that work. Keep it simple!
Well anyway I captured some gameplay video from the TV out on my HD-PVR, and some screenshots from my iPad... yep my iPad still needs to be used, and the game shows a very different display to the TV.
iPad captures:

So thats what you see on your ipad.
The top right icons are:
105mm - Big Badda Boom - slow to reload and one shot every couple of
seconds.
40mm Cannon - still a badda boom but not as badda as 105, upto 5 rounds per reload and fast fire.
25mm - rapid fire mingun, lots and lots of bullets an highly accurate (ish!)
If you didnt have TV out, this is what you'd see on the screen instead...
