In the new revision of MK4, currently testing at Diversions and Dennis' Place for Games in Chicago, the Kombat Kode 001-001 now gives you Unlimited Run, and 010-010 disables Maximum Damage. Reports also point out that Quan Chi's new weapon uses existing animations used for Raiden's mallet, "motion swapping" is very easily done with MK4's engine. Also, Kai carries the Ghurka Kukhri (Machete) as his default weapon, which was Quan Chi's, Cage has a new sword that's reportedly simular to Jarek's Scimitar, and Sub-Zero has been slightly weakened. Thanks to Da Sawman.
