Fun game, more of the same.
DISCLAIMER: Only played this with iPad, though I did play the original KR as a gog release.
Have you played the original Kingdom Rush?
If not, it's really good so go and play it. Really, superb tower defense.
If yes, you already know what this is, so if you want more of the same, it's well worth getting.
This one brings in a ton of new turrets, units and enemies. As gameplay goes, it's every bit as good as the previous one.
But it's... slightly less fun somehow.
Maybe because it IS more of the same, or maybe the new units aren't quite as interesting.
Or maybe it's the new heroes that are not up to previous ones standards..
