Sub Zero Preview released.
I downloaded a Zub Zero update earlier this evening. 18 new races… the familiar three race modes (3 modes x 5 races each) and instead of unlocking a new character you get 3 slalom races to complete solo against the clock.
There's just the one track... down a snow covered mountain!
There's also just one bird coin kart. All of the others require gems, starting with just 100 gems and going up to outrageous amounts.
It's pretty fun, but if you upgrade your cart to the max (which I did before my first race) there's not much of a challenge.
