This is my opinion
I Think this is Fake ! Why ?
When viedeo beginn is the gGock set on 05.44 when he Launching the Multiman.
And when he play the game DOA5 is the Glock on 05.42 !!! Very Strange
And the Multiman say Change the Parm.sfo on 3.55 and when the Team have Realy the new Keys and e way to Jailbreak 4.21 why is the Viedeo so shortly ?
But this is my opinion
