Found a block infinite with Cyrax 30 minutes after the game came out lol.
For this to work your opponent must:
- Have no meter
- Be cornered
- Be a "heavy" character (ex. Goro, Ferra/Torr)
NRS PLS
EDIT - AS OF THE 3/8/16 HOTFIX, THIS HAS BEEN FIXED. 212 CAN NOW BE NEUTRAL DUCKED BY EVERY CHARACTER.
