Back in October we reported about Freeverse, the makers of Marathon for XBLA, bringing their Mac OS X party title to everyone's favorite downloadable game service :)  Well today, were happy to hear, both Freeverse and Strange Flavour have decided to pull back the curtain a little further with the screenshots found below of the upcoming Airburst.  While I'll admit I've never tried the original version (not having/wanting a Mac kinda got in the way :) ), judging by the screenshots (always a weary thing to do) this one looks like it's going to be pretty damn good.
