5 0 1Do under 40 target actions in Arcade mode & you will encounter Billy on the 4th stage, so try to do as few target actions as possible.Showing only comment. Leave a comment. Over on XBA NeoStrayCat says that it has to be under 20 target actions. This must be the case, considering I didn't fight Billy nor did I fight Saiki my first play. Therefore they can't both be 40.Posted by Sanada on 23 May 14 at 15:24 Leave a comment
