I picked up Novastorm today at Electronics Boutique.  I was a big fan of
the 3DO version, which was labeled "shooter of the year" for 1994
according to Die Hard Gamefan.  The Playstation version is the best
version of Novastorm out anywhere. The game has been almost completely
redesigned.
 
New Additions to PSX version:
 
Full screen Gameplay
Crystal Clear FMV/backgrounds
Better Control of Scavanger X
Improved Techno/Rave Soundtrack
More Bosses (much bigger and badder, very clear also)
Better weapons
Fully interactive (you go over mountains and bob over/under scenery
Awesome Full Screen Cinemas throughout game
Detail enemies, and lots of them
 
Overall, this is a classic sci-fi shooter that is at least worth a rental.
 The game is fun! I know some people just don't like FMV shooters but PSX
Novastorm takes the genre to a whole new level.  Anyway, in a horizontal
shooter the backgrounds are completely uninteractive, but people love
horizontal shooters.  Novastorm has your ship going "into" the scenery:
you can hit mountains, swerve under and over obstacles and more.  This is
my favorite shooter for 1995.
