I've played it a little bit and have come up with a list of things.
--This game makes up for the debacle that Rengoku: Tower of Purgatoy was. (you can actually strafe and fight more than one enenmy at a time)
--The homages (blatent rip-offs?) to Tron and The Matrix are easily seen (down to the cascading green code and the hacker invading a secure system motiff)
--This game, while fun--gives me a headache due to the vantage point.
--The enemy AI is unpredictable and some enemies will bum rush you.
--The game takes ten seconds to load each area (of course, like Resident Evil, this is "part of the atmosphere"
--Unlike Metal Gear Acid...you can actually skip sequences that you don't want to see for the umpteenth time.
--The weapon/defense system allows you to mix and match program attributes; ala Tron 2.0
Probably makes a great multi-player...
