Wanna Go Moon Diving?

This looks like 4-player Strider to me.  If so, that's amazing.

I really hope that was a RealUltimatePower reference, because I'm ready to get pumped!

I almost had a epileptic seizure there at the beginning. 

More like StriDiver.

This looks like 4 player Kabuki Quantum Fighter to me. Which is kind of disappointing since blades and 4 players makes me think of Guardian Heroes.

And now, I'm sad.

Co-op platformer? mite b cool

Looks like a Japanese Castle Crashers

Whoa, I didn't know they still made trailers like this anymore. I thought I was in the 90's for a second when I just saw gameplay footage with a random song playing over it.
