Lots of new content on the Nintendo eShop on the Wii U in the form of two newly released demos.

Zombi U is now available for you to try out on the eShop channel, letting you experience Ubisoft’s first-person survival/horror game before you buy it.  In addition, you can catch all the fun dunking antics of NBA 2K13 as well, as 2K Sports has released a demo for it, too.

If you have a 3DS, you can download a number of new games, including Reel Fishing 3D Paradise Mini, Wild Adventures: Ultimate Deer Hunt 3D, 101 DinoPets 3D and Hello Kitty Picnic with Sanrio Friends.  We’ve been waiting forever for that one!

Another old-school game from the Neo Geo library has also arrived for the Wii, in the form of World Heroes 2, a fighting sequel with characters from all over the world.  You can get it for 900 Wii points ($9).

Finally, DSiWare has a new game, the puzzle game Biorhythm, which’ll set you back $1.99.

Happy downloading!
