Na, I haven't. It's on my radar, though. I'll pick it up instantly if I ever see it. Not only because it's Contra 4, but Wayforward made it and I enjoy their stuff.
Have you played Contra: ReBirth at all on WiiWare? That was a pretty solid Contra game. Definitely had the Contra difficulty! You can play it like an arcade game, though, and keep continuing, but if you tried to play legit it would be quite the spectacle.
That samurai girl was the only DLC character, except for Browny, that I was interested in, haha. I figured that would definitely switch up the game!
