my most anticipated game of 1st half 2015 after splatoon and yoshi. just played the first mission. it's good. *really* good. a nice mix of action and strategy, with a bonkers alien-invasion story, comic-strip graphics and a ridiculously well-developed and well-implemented "steam" mechanic...
from what i've played this deserves kid icarus: uprising sales at least, if not fire emblem: awakening.
