Just picked it up, & it's great! IMO, probably the best Contra in a looong time. Actually, I think I like it better then Contra 3. I haven't beaten it yet, I'm playing on easy, & it's not a difficult as everyone has led me to believe. Though, I hear normal really bumps up the difficulty in comparison. But, I want to atleast beat it in easy, so I can start unlocking Contra & Super C. I think it even has the 2 old Probotector's on it, though, I don't think they're that much different.
