Arc System Works has released the first trailer for the upcoming remake River City Ransom SP.

The game footage shown reveals that the game will use classic pixel graphics for the characters, but with remade 3D backgrounds. There also seems to be a new fighting system, with the characters pulling off new moves not in the original.

River City Ransom SP is scheduled for release on the Nintendo 3DS in Japan this spring to commemorate the 30th anniversary of the series (known there as Kunio-Kun). No international release has been announced at this time.
