On this page of the Deathloop game guide, you will learn whether you can change the appearance of the main characters - Colt and Julianna. We also answer whether the new outfits affect the character's stats or if they are purely cosmetic items.
Deathloop lets you change the characters' appearance, but finding this option isn't very intuitive. On the preparation screen between missions / invasions, you have to hover your cursor over the character and confirm that you want to change their outfit. This will take you to the clothing selection menu.
The costumes in the game are cosmetic only (they're skins) - they don't affect the stats of Colt or Julianna and they won't give you any additional abilities. Unfortunately, since the game is played from a first person perspective, you can only admire your new garb between missions.
By default, you won't find any alternative outfits in the clothing menu. New outfits can be obtained by reaching higher Hunter Rank levels as Julianna, i.e. by participating in online invasions and achieving Julianna's feats .
If you ordered the Deluxe edition of the game, you can receive unique outfits as a gift. For more information, check out the Game editions page.
