Mortal Kombat's Challenge Tower mode is among some of the most insane things I have seen in a fighting game. The fighting script will change dramatically once you delve into this tower with the stipulations and obstacles Netherrealm Games will throw at you. Fighting with no arms, no head, no jumps, flaming floors, and killing waves of zombies are just examples of what to expect here. I'll let the video above explain more about it though, but this is nuts. Mortal Kombat is still coming out next month and looking pretty good so far.
