Nintendo Co. President Satoru Iwata has delivered his clearest message yet to gamers about the company's future: Don't count the Wii U out yet.

Nintendo, threatened with becoming an also-ran in the market for home consoles, announced a half-dozen new titles for the Wii U in an online presentation for the annual Electronic Entertainment Expo in Los Angeles, including a multiplayer shooter game called Splatoon and Super Smash Bros., and unveiled a collectible-toy platform for the console called Amiibo, similar to Activision Blizzard Inc.'s Skylanders.

The maker of Super Mario and Zelda has struggled to revive sales of the Wii U after missteps including delays in getting key titles to stores. The Mario Kart 8 racing title sold more than 1.2 million units globally during the last weekend of May, and Nintendo is counting on holiday releases to build momentum for a console many analysts expected the company to write off.
