After their recent announcement of the collaboration with Street Fighter 6, SNK waited a little before giving us more to go off of than just some teasers and images.
A new video on the official King of Fighters ALLSTAR channel shows the full collaboration previous. No gameplay, mind you, but it's still a neat animation that shows off the models and choreographs a little fight between Cammy and Mai, as well as Guile vs. Yori.
This isn't the first time KoF ALLSTAR is collabing with Street Fighter, but this time it's specifically the sixth series, with the last one being based on Street Fighter V.
Who knows, at this point it seems likely that Tekken would get another collaboration as well, possibly featuring the newcomers from Tekken 8.
