Alternate costumes provide a visual customization option for your favorite characters. Each character typically has several alternate outfits, ranging from minor color palette swaps to entirely new character models. These costumes are purely aesthetic and do not affect character stats or abilities in any way, but they allow players to express their style and preference.

How to Unlock Alternate Costumes:
- Arcade Mode Completion: Some alternate costumes can be unlocked by completing Arcade Mode with a specific character on certain difficulty settings or under particular conditions.
- DLC Purchases: The majority of alternate costumes were released as downloadable content (DLC) packs. These packs often included multiple costumes for various characters and could be purchased from the respective platform's online store (e.g., PlayStation Store, Xbox Marketplace).
- Special Events/Promotions: In some rare cases, certain costumes might have been available through limited-time events or promotional offers.
Once unlocked or purchased, you can select alternate costumes for your character on the character select screen by pressing a specific button (often Punch or Kick buttons after selecting the character) or navigating to a costume selection option.
