To me, this game just doesn't feel like Contra and more like "another Japanese clone".
I enjoyed Contra: Shattered Soldier on PS2 or even Contra: Hard Corps on Genesis (not to mention the original) ~SO MUCH MORE~
I've had great hopes for this game, since there's really not enough side-scrollers like this lately, but I ended up displeased and the more I played Hard Corps, the more I wanted to turn on my PS2 and play some C:SS.
I'd rent it, if that would be possible. Can't recommend a buy, unless on some special offer or if you have the craving for Contra-ish game and all your other copies got eaten by a dog or you chewed through them thousand times already.
