Improve the strength of your party by adding characters that you can get for free!
FFXIV – Anime Campaign EN PEGI (30s)
Like Genshin Impact, Honkai: Star Rail uses the same mechanic where you collect characters that you will add to your party.
Right now there are a total of 27 playable characters in the game.
However, most of them are not available for free. In fact, only about 8 of them can actually be obtained for free. That said, you can still take advantage of them if you plan to play F2P.
