As Hector mentioned on the PAX East stream, there were several high level players who were brought in to test out Injustice to make sure they could help with development and balance. Arturo Sanchez and NerdJosh of Team Sp00ky were two of these playtesters. After the showing of Injustice on the PAX stream, Arturo began answering tweets concerning how certain characters play. Needless to say he was bombarded with tons of questions. Here are a few of his answers.
If you have a question about Injustice that Arturo might be able to answer, give him a follow (via nycfurby)and send your questions!
