I think they are kidding you.
How did this happen? It seems impossible.

Really impressive stuff. Bravo

Jumping around in unison isn't my idea of hardcore gaming. Custom maps on Halo require more skill that this crap.

Looks like it's being played by 5 PS4.

You serious? Shit like this takes ridiculous amounts of skill and practise. Mario U is packed with challenges like this, just watch some of the shit on Youtube. It's amazing how much they actually put into a game like this. 

Don't feed the trolls. ;)

Absolutely impressive gameplay by passionate pro-gamers!

Talk about an accomplishment !!
I was playing with my niece and we were able to beat all stages playing co-op. I never felt so satisfied in finishing a game in co-op play like this. We didn´t get all star coins yet, though....
Then I called my brother and my nephew and after a few tries we did beat Bowser with 4 players.

Halo is for immature teens pretending to be adults.

This one is for real skilled players.

wow, i am not that sharp in mario anymore haha. I feel like a noob these days compared to my childhood lol.
