Check your inboxes for The Legend of Zelda: Tri-Force Heroes demo codes. The game launches on October 23rd, with Nintendo stating yesterday that demos would be available on the 22nd. However, seems demo codes are being mailed to selected peeps—I just got one (& 2 more to share with friends) along with a notice that online co-op mode will be available to try as well on 10/16: 5 p.m.-10 p.m. PT, 10/17: 5 p.m. - 10 p.m. PT and 10/18: 7 a.m. - 12 p.m.
