I remember playing the original, but this remake is WAAAY better. Competitive mode has just been announced in addition to the standard cooperative mode.
It is sure to clear 4 million, but only 7 hours left for the Kickstarter. Not to worry, this one is bound to make retail release. The expansion should also make the shelves.
