Found through Blue's News Feb. 11 update:

Not sure if it's a new review (also, apologies if it's been mentioned before.)

While he's otherwise quite positive about the game, the reviewer counts off originality points for the use of "zombies", which I find debatable at best. (After all, how would you expect corrupted programs to behave, except as if they were *damaged* somewhat?)

He also praises the "unlockable" disc arenas, which is news to me...must do some research on that, I suppose.

Thanks, programs!
