A little over a week or so we mentioned that Radiangames were bringing many of their excellent XBLIG titles to PC and Mac.  That day hath finally arrived.  You can head over to the Radiangames website and pickup the Quadtastic Launch Collection for $11.99.  For $14.99 you can nab the Super Radiangames Collection which includes Super Crossfire.  We had the privilege of previewing the collection, and I can honestly say the staff was quite pleased.  Check out trailer above for gameplay footage of the collection, and you can check out our previews below:
