What I want to know is why, at level 24, with maxed damage, range health and speed, as well as the powered skills in their respective groups, still manage to practically get instant killed as a 7,000 hp bomber jet, along with all the other flying (non-helicopter) units. Near impossible to complete this flying battle. For this alone (not just happening in this level) I give you 2.5 stars for the glitch because it is overly annoying. Otherwise addictive and easy to play.
