Looks amazing!!
This seems like a good blend of uncharted and left 4 dead, and seeing as how nintendo has none of those hits, it was an amazing idea to support this as a new ip in collaboration with a third party company.
As a free to play, multiplayer game, with an appeal for most ages, I can see this game reaching high popularity due to word of mouth.
Bamco will also probably make a great amount of money releasing quest expansions at $10-$15 each, with probably 1 or 2 to play for free.
If I had to guess, the graphics and quality are fairly low due to this game running online (would be huge for this game) and still being in development. As a free to play game however, many won't also make a fuss about the graphics, and the low quality would allow bamco to make great expansions at a fast rate.
Good job Bamco and Nintendo, but there is work to be done
