Play As The Female Luchadore Tostada In Single Player
Tostada is a character only normally playable in co-op, but using this method you can play as her in single player. She has the same attacks but the animations are different and her moves have a lot more finesse. You will need two controllers for this: 1. Playthrough the prologue until you get to the part where you get the mask and the female luchadore appears. 2. Press Start on controller 2, burst the bubble that appears with Juan, this will make the female luchadore appear. 3. On controller 1 press R1 twice. This will revert the game to 1 player but with you playing as the female luchadore on controller 2.
