changing outfits and weapons?

[Nexus]

i got the templar rifle and the arbaaz outfit but i have no idea how to equip it.

do i have to be at a specific part in the game or is there some kind of menu or...?

you might have already stopped playing or figured this out, but you can go to settings -> Extras and equip the outfits you want to
