For a sprite movie, the action itself's not that bad. There just wasn't enough people to shoot, however. Just Luigi, Toad, Peach, and Mario? This kinda makes your title misleading as it has nothing to do with Bowser and the Koopas. And no music, even? Though I'm well aware that CS (which it doesn't correctly imitate, as CS was never a free-for-all deathmatch) has no music, it really downplays on the lack of shooting action.

If this movie had more action, and with a more detailed backdrop, this'd score a lot more points.

Its a new twist to Mario. Great Job

yo dude, hit me up on msn or aim or something. I'm working on Part 2 to a flash I did. I gut some question for yeah. Check out 1up in my flash movies. Tell me if you wanna help?

The graphics are alright, but basically it was just Mario, Luigi, Peach, and Toad killing each other. Luigi's little head boogie thing at the end was a little funny (the "moral" at the end was OK too), but that was all. This is just fanservice for the blood-loving Newgrounds users.

tell me did you get the idea from a show called Trigun.
