I highly doubt that this would happen, but it would have seemed logical if it was possible to unlock any bonus features in Echoes. Link Corruption with Hunters, via the wireless DS-Wii connection. Complete Corruption, and you get to play Super Metroid using the Wiimote and Nunchuk. Complete Hunters, and you can play through Corruption as any of the 6 hunters (of course this would only be in appearance). Any other ideas?
