The KO #36 - Ryu (and Ken) in PS4 Alpha 3 Dramatic Battle!
3Playing the hidden, 2-vs-1 "Dramatic Battle" mode in Street Fighter Alpha 3 in the Street Fighter 30th Anniversary Collection on PS4; you start Dramatic Battle mode by holding all three Kick buttons and pressing Start while the Alpha 3 intro is rolling (I learned how to do this from the info screen accessed with the Triangle button on Alpha 3 in the 30th Collection's game select screen. : )
It's kind of a boss rush mode, with a CPU partner (I think a second player can join in?) but it was way easier than I'd expected, in large part because when you pick Ryu, as I did, you get Ken as your CPU partner, and he goes absolutely HAM on the opposing character, so as Ryu you can just sit back and chuck fireballs--just be sure to burn your supers pretty quick, though, otherwise Ken will burn them himself and he isn't very accurate with them. : P
Turns out this is also a quick way to get the "Beat Alpha 3" PSN trophy for the game!
