Sf6, Unlock costumes in World Tour Mode... OK

$5 

$5 for 5 alternate costumes.

UPDATE: Personal experience is... while it's slightly interesting, I am weirded out by this crime-city environment quite a bit. It's taking forEVER to get anywhere also. In 2.5 or 3 hours, I did part of the Chun Li thing, saw the Marisa giant in Italy... and I think that's it. I'm constantly lost and running in circles trying to find the rooftop ladder, the entrance to the fenced off area (I jumped in one time after like 30 minutes... only to find a walkway out once I was in there???) and junk like that. I really should just pay the $5, but it's like some annoying "challenge mode" that makes me want to beat this thing. The one good thing that came of it was getting a million Zenny coins to change the look of your dude... so I made him super stretch tall/long armed dude so I can fight better. OMG, in Chun's stance, the standing or towards Strong and Fierce are ridiculous. Bison's moves are still the easiest... slide and hit them all. 

This guide explains the one time only SUPER GIFTS for 40 pts. vs. the other decent gifts 5 pts. vs 2 pts.:

Zenny farming and if you do the Akuma 100 bond thing, how to deal with it: https://gamerant.com/street-fighter-6-where-to-find-akuma-in-world-tour-outfit-reward/

Zenny, a great way to farm some quickly is by heading to the Southeast part of the map in Metro City to the Scrap Heap minigame. The highest difficulty can give you 15,000 Zenny in less than 30 seconds. The hard mode can take quite some time if you are new to farming it. A great strategy is to switchto Marisa's Fighting Style and starting the fight with four heavy punches followed by four Down Heavy Kicks and then Heavy Punches till the Truck is destroyed. This method will guarantee a lot of Zenny per run.

Classic Costumes

Some costumes (((all classic costumes looks like))) can also be unlocked without having to use real money or in-game currency, but you are required to play World Tour mode to do it. Be sure to look over our Street Fighter 6 Masters location guide to find your favorite characters and get their Outfit 2.

***TRICK TO do the story mode quicker, avoid gangs slowing u down, PhoenixWright said:

I know what you mean. During the first chapters it can be very rough and annoying, in early game it helped me fighting "The Watcher" as he's at level 28 and very easy to beat even at a low level, cheap trick to level up fast and get those annoying mad gear dudes off your back.

Other:
Shower them with gifts, especially the ones that raise their bonds by 5, there's a list somewhere. Get 20 of these and voila. Can be purchased at various npc stores in the general/food section with in-game money from playing world tour or doing the mini games like breaking planks.

AKUMA

SIDENOTE: Do his secret taunt once, get two or 3 new secret supers?!?

Press all six buttons while pressing left and he sat down, then do the same inputs but press down instead of left and he will eat...wait... 

• QCBx2+LK and he did the SA. You only have to do the taunt once (did it in training).
• And double hado while in air with 63214 PP.
• And Down+down+PPP, another super.

Eventhubs: From our testing, you must hold down and continue to press all three punch and kick buttons (just the taunt input) after the animation starts. You don't have to mash super hard since we found pressing the buttons around every 30–40 frames or so seemed to do the trick consistently.

Once around ten seconds have passed, Akuma will actually pull out a rice ball and start eating with his back turned. At this point, you can stop pressing the buttons.

AKUMA, basically is the longest one to get (Maybe Bison is bad, too):

Alternative unlock method: Develop a level 100 bond with Akuma in World Tour mode. You can do so by offering him gifts and completing missions for him.
Preferred gift / purchase location: Fishing Hook = 40 bond pts / Complete the Busybody Decoy mission to get this item.
