Contra 4 for Nintendo DS →[More:]
This is a REAL Contra game that feels just like Contra for NES or Contra III for SNES. First new game in the series since the SNES game that does not miss the mark.
It uses both screens which can be irritating (you can be shot by something on the top screen so you have to watch both) until you get really used to it and if you have not played anything like this recently you can expect to have trouble finishing the first level until you get back into practice. Definitely harder than any of the newer games I have played lately but not much harder than the original Contra.
It is going to be sucking some of my gaming time away from WoW (yeah some of my LotRO guildies finally talked me into trying it) and the other new games I have will likely be ignored for a bit. I doubt I will clear this one for a while as the difficulty is enough to make you want the Konami code (I haven't looked for cheats, the damn thing might even work) for 30 lives.
Despite not spending much time on them yet, I can also recommend Bleach: The Blade of Fate (fighter based on the Bleach anime) and Puzzle Quest, both for the DS as well.
